Two things came to me after rewatching THE game.
1) Any one else notice that the coaches called specific plays for each and every player that fumbled shortly after we got the ball back, and when they could? Meyer is a master of psychology. No doubt this is part of his scheme.
2) Notice the tackling and form? Our players no longer try to stand up ball carriers one on one and try to drive them back. They now simply wrap and drop, taking the carrier down with them. This has got to some type of wrestling technique.
