I'm ok with it at a pro level and even high level college D because you have extremely fast and powerful players. I agree a 225 pound guy that can run can both cover and run stop pretty effectively. A 195 -205 pound guy in college not so much. They can't effectively rush, can't get off blocks or stuff power backs. We have seen all of this - no effective blitz pressure, big run gashes, missed tackles at the legs and poor cover. I think Crocker's IAA scheme works there because players are generally slower, so the speed edge is magnified even if the guys are physically smaller. A blitz off the edge is much more effective with a slow big tackle. At D1 level, the speed is notched up even with lineman. Any way, as long as it works, it works. This year was a historically bad fail by any reasonable standard. I don't believe Crocker should be around and rewarded for the very worst DC performance in FBS, but stubbornness is Edsall to a tee. Maybe they find the "right players" for it.
