Libby needs a grappling coach. Rikako Yuasa could be a great coach for her. She used to offer summer seminars. Once Suda got Libby on the mat, Libby was helpless. Like the Korean commenter pointed out below, Libby's earlier opponent, Momoko Yamazaki had a glass jaw, so Libby could easily defeat her. Suda is far tougher than Momoko. Libby also needs more power and muscle. Suda didn't feel any of Libby's punches. I have faith in Libby that she can improve but it will take a while. 🤔
