[@carryutru2454]

+Justin Gillen In this case your MIT professor THEORY doesn't apply because this was about one: if they cheated.Which the Wells report proved they did and two if Brady was aware of it and WE ALL KNOW HE WAS. Hence why Goodell took action and those two equipment managers are gone and he's still after Brady. Yea, if it was as simple as science to answer then Goodell would have not needed a investigation especially when it's involving a team who is NOTORIOUS with cheating and then the investigation actually shows proof they were guilty of what was being reported. Only question science can't answer is was Brady involved? But you don't need science to answer that when you think logically about it and ask what other reason would two adults who make far less than Brady and whom can be easily replaced would risk their family livelihoods to give a multi-millionaire and billionaire an advantage in a game of the magnitude of the AFC championship, unless they had been under duress or incentive promised.

[@JustinGillenMusic]

+Carryu Tru Wells report did not PROVE they did anything. That is why when it went to court, everything fell through for the NFL and their "investigation". And if they did not do anything, then there is nothing for Brady to be involved in. What proof showed they were guilty? Speculation on cheating? Have you read the court transcripts. I am actually interested in your response. Because fans of other teams are NOTORIOUS for crying wolf every time this team does anything. Then if they lose, its because they aren't cheating anymore. My statement is meant to express how quickly people jump to conclusion because they want it to be true. They want it to be true, because it brings a success powerhouse of a team and a quarterback down to their level.

[@jaredtaylor7700]

+Carryu Tru The ignorance runs deep in you my friend. Your hatred for the Pats clearly makes you incapable of reasonable thought. You say the Wells report proves that they did it. Then why did all the experts say on national television that if you support the Pats, you can find information in the Wells report that exonerates them, and if you don't you can find information that supports your theory too? A report that "proves" guilt should not be able to support both sides of the argument. It should be clear and concise and should not be able to have holes shot in it like have been done.

[@christopherobrien2675]

+Carryu Tru read the Judges decision overturning the suspension of Brady. Your reasoning is so bizarre - if the balls naturally deflated due to the conditions, then "was Brady involved?" is not a question. That's like saying a man dies of natural causes, but was the wife involved with killing him?

[@jaribe101]

+Carryu Tru please give me facts that support your "notorious for cheating" allegations other than spygate which im sure you have no idea what is was about but you blind hate wont let you educate yourself. Everyone says they cheat but can never give the actual proof of cheating. tell your team's owerners to make better decisions to stay consistent and move on.

Last years superbowl was the most remarkable in a long time. The game was intense and close, and the underdogs won it while the pats fans were like "I forget why I'm a fan of this team" because their shoe-in lost. This years was vs a team that shouldnt have made it to the superbowl where neither team played well and in the end when everyone woke up and saw that the Pats won after falling asleep during that boring ass game they were just as disappointed as the Pats fans were happy: not very.

[@UndertakerU2ber]

The thing is, the two consultants hired in the investigation both independently concluded that the Ideal Gas Law and similar theories can’t fully explain the deflation of the Pats’ balls. The two were an engineering and scientific consultation firm, and the other was a Princeton physics professor that formerly served as the chairman of the physics department. My guess is that those two parties had access to additional data provided by the NFL that wasn’t available to the professor in this video. I doubt the two entities in the investigation would deliberately tarnish their reputations over petty football rivalries, so I’m more inclined to take the conclusions of the consultants at face value than what this professor concluded.

[@joemagarac405]

@@UndertakerU2ber Jeff Benedict in The Dynasty gives a really good round up of this non-scandal. It was bullshit from the beginning cooked up by a salty Ravens coach. The NFL realized its mistake about midway through but doubled down because that’s what they do in a scandal. Brady wouldn’t let them have his phone because he already seen how peoples texts were leaked because the NFL couldn’t keep anything a secret. I’ll take an MIT professor over any hired gun consultant any day. This guy is doing this just as an exercise for his students and is impartial; any engineering firm hired by a third-party is going to try to cook its answers to suit the agenda of the people paying them.

[@700Ezalb]

@@UndertakerU2ber Those consultants are right, the IGL doesn't fully explain the Patriots' PSI drop -- that's why you also have to consider the weather and factor in the leather of the balls expanding due to them becoming wet. The volume of the football increases when they get wet, leading to additional PSI drop. As John Leonard explains in the video, it's the Colts' footballs that didn't match what the IGL predicts, and that's because they were measured at the end of halftime -- they were allowed to warm up, and they were also kept drier than the Patriots' footballs were, so less expansion of the footballs due to being drier.

[@Rowgue51]

One thing he forgot to mention is that the miniscule difference in pressure they're alleging is completely explained by the mere act of measuring the pressure. Every time you stick that needle in the ball you're losing as much pressure as they're saying they were deflated by.

[@Rowgue51]

@hue bolser Air has to go out of the ball and into the pressure gauge in order to measure it. There is also air the escapes from the process of inserting the needle. And with something as small as a football there is very little volume of air your dealing with. The smallest amount of air being released from the ball will make a vastly more significant difference in pressure than something with as much air volume as a car tire. But this is something easily observed even on a car tire. Take a pressure gauge and measure it. You measure it one or two more times and I guarantee you will be reading at least 1 psi less than your first reading

[@Rowgue51]

@hue bolser tested. You're wrong

[@ppumpkin3282]

the operative word is "miniscule" - no one suggested a one pound change everytime you measure, by the way, the Colts team measured the ball that was intercepted - which is illegal under NFL procedures - who knows how much air they took out when they tried to rile up the league.

[@evanm8]

Footballs received by the team are often over inflated and need to be "deflated" to 12.5 psi. Just because the equipment manager jokes about deflating, and mentions Brady yelling at him for having a game ball over 13.5 psi doesn't mean any rule was broken (or if so, that Brady was aware.) It could simply be that Brady told him to make sure balls were never over-inflated again.

We have this problem all the time in Europe regarding soccer/footballs, especially in COLD weather, where you fill the balls indoors in nice ordinary room temps. And the moment you bring the balls outside and start to kick them around, they deflate rather quickly - they become "heavier" to kick around on the field. Many people erroneously believe it's because the leather get's wet, but that actually isn't the case.

[@Sailor376also]

My calculations came to exactly the same results. Your logic and methodology I think are correct. One item that you did not touch upon or only briefly. Locker rooms are a notoriously humid environment. The balls were certainly,, not maybe, filled with some level of water vapour. So exactly where you filled the balls, prevailing temps AND humidities interior to the ball, can make a massive difference. Not a small difference,, I have dealt with aircraft takeoff calculations, hot and humid air is crash and burn air. The weight limits, rotation speed,, and especially the length of the runway all come into play. A cold dry day ,, you can load the begeebers out of the aircraft,, a hot humid day, you do not put an extra liter of fuel 1kg, into your tanks for fear of being too heavy. Footballs exterior and interior are subject to the same physics.

If Tom Brady loves the footballs at 12.5 psi, and if it was as cold as it was during that game, OF COURSE THE BALLS WOULD DECREASE IN PRESSURE AND BE UNDER THE REGULATED PRESSURE

[@MegaDjernesto]

091MW2 if it was a bit colder so would the colts balls💁

[@mitchcomedy2112]

ernesto neri if u would have listen to the video the Colts footballs PSI also went down the only difference is that the Colts football was at 13.5 at the start

[@nokomisnorth8409]

WeeBeeTalkin TV well and the colts balls didn’t experience the long drive in the rain at the end of the game, instead they were in a bag on the sidelines to stay dry. If the colts were exposed to the same elements on the final drive they would’ve gone down to reach the gas law and also if they were measured at the same time as the patriots balls during halftime as compared to patriots at the beginning and colts at the end, they would’ve both been under 12.5

Excellent analysis prof... Now we need you to get back to providing the calculations for 'Diverting the meteorite from hitting the earth and wiping out all mankind project"

[@dash4800]

Obviously the science has been proven. But the thing that amuses me the most is the logic behind how they would have used balls, deflated at different increments, cheat. First off, they would have to know which ball was which, which means they would have to be marked somehow, which the refs would notice. Then they would have to have a foolproof system implemented, in which when they ran into a specific scenario, they could bring in the super low pressure ball to give them an advantage on this unstoppable play. It's completely ridiculous. The only other way you can say they actually cheated is to say that Brady simply wants his ball flatter for grip or something, but then having 12 balls with a 2 PSI difference randomly between them would completely defeat the purpose of that. You can logically debunk all of this before you ever even get to the science.

[@theoriginnone2753]

+dash4800 This guy lost all credibility in trying to apply the ideal gas law to an expanding and contracting system.

[@xYondaimexJD]

+the originnone you lost all credibility when you don't understand the limits of expanding and contracting systems and how negligible it is within the context of the system being studied....

[@theoriginnone2753]

It' slightly more significant than the negligible difference due to the wetness on the balls prior to bringing them inside. Do the math. It's pretty simple.

[@jimmylozano4261]

Paul Morales The answer is, the colts balls had not dropped yet- as evidenced by the outcome of the game.

[@Smullet90]

I work in gas measurement and this was the FIRST thing that came up in our conversation. It was so obvious, heck, any kid on the playground in a northern climate knows that balls lose pressure in the cold. Simple solution would be to air up the balls under ambient conditions.

[@v1ct0rh4n7]

Okay an eagles fan defending the patriots? Ultimate reason that both Tom Brady and Robert Kraft should've appealed further than they did

[@grogery1570]

It was all political. Goodall likes his job, to keep it he needs to keep 3 or 4 owners onside, the ones that actively participate in running the league. Ironically that includes Kraft. If you ever wonder why so many decisions go Brady's way it is the relationship between Goodall and Kraft. On this occasion everyone saw a chance to break the Patriots dominance so Goodall went after Brady. The end result, Goodall keeps his job, Kraft and Brady keep wining super bowls

[@Datboy1991]

Brady pushed it as far as he possibly could. Language of the cba just makes it impossible to challenge Goodell.

[@-Tac0caT-]

Another interesting experiment would be to assume that the NFL is correct, and yet still apply the Ideal Gas Law. With a needle in a bathroom, is it possible to remove so little amount of air consistently, and disregard the whole wet ball dry ball debate? I guess I have never seen what it means to release the claimed amount of air from a ball.

[@mateogcolon]

Why is his whole presentation in comic sans lmaooo

[@klk1900]

I started playing qb at 5yrs old. I always have been obsessed with the air pressure. Even in high school I would sneak extra air into the balls. The more air the faster,higher,farther,more accurate I can make the ball fly. Underpressured balls are like throwing a wet towel around. It’s sluggish as hell. Even today I’ll take my nurses out and we play catch football or baseball. Just depends on the mood. I still like over pressured balls. The just fly like bullets. Underpressured it’s like what I call wobbling goblin. It’s gets a strange wobble. So I can’t see someone deflating balls to try and win a pro game. Talk about increasing the chance of interception. Now you lounge lizards that play video games probably have no clue what I’m talking about. 99% of these kids have only seen a football on TV.

[@jay-ki6ie]

klk1900 no one ever brings this up. why tf would you even want deflated balls?

[@ssj4gogeta77]

The fact that Brady’s argument in his appeal became that the Goodell obtained evidence illegally tells me that he did in fact do it. This professors argument can’t be completed because he doesn’t have all of the information readily available

[@pdizzle5302]

He did

[@gregorypcampbell]

why don't you post a response video and show us all how the calculations were incorrect.

[@originnone]

Why don't you do the math yourself? Then I won't have to.

[@gregorypcampbell]

nah... I can admit that I wouldn't know if either one of you were correct

[@MattyDemello]

Its true. I can confirm that cold weather will definitely interfere with air pressure in a ball or a tire. So it was -7 degree's where I live for a cold spell but then the very next day it jumped up to 38 degrees. On the day that it was -7 my tire pressure light came on saying my tires were low on pressure. The very next day when it warmed up by tire pressure light went off and it was perfect.
