But, to be critical of practices last year (assuming you weren't in attendance) is senseless. How do you know what was done during practice.
We know OK drill that brings the intensity and we also know that was done based on multiple videos posted throughout last year.
However, I like this (especially for the O Lineman & D Lineman) drill just as much, even more in some ways. Just as intense and less chance of getting hurt than the OK drill. Not to mention the team camaraderie & toughness it builds. The other thing this does, it gives them something new. Part of coaching is finding new ways to challenge the guys and this one does just that.
