We've gone from use of belts and straps, to always needing to go to 90, to back bend, which has now become back curve. It's probably not on the level that you've experienced, but here's another video. It's max day at Indiana, maybe not a top level DI, but it's DI. A lot of different technique even within one room. Not one single squat below 90 and damn few getting parallel. Plenty of bend at the lower back with a few and some with knees buckling inward. You obviously have some experience, and maybe you played and perhaps coached at the DI level, but I don't think strength training at the college level is as strict and perfect as you believe it is. No disrespect intended and I really do appreciate the concern for the kids. This is absolutely my last post on the subject. Most of the time I regret ever coming on here and yet I get sucked back in every time.
