Last year, I went to a Saturday scrimmage they had the week before the season opener. It was obvious they were dead. There was very little life and players were just walking around slowly and doing a lot of standing around. Quite possibly the most boring practice I've ever been to. No question the approach is different. Tuberville's philosophy seemed to be a war of attrition. We're going to bust your fucking asses in the heat until you drop and whoever is standing at the end will play. Chizik seems to have a different approach, and with the lack of depth at some positions, that may be wise.
I have no idea which approach is better and I'm not dogging CTT or pimping Chiz. Some corches are old school and others have different ideas. But, don't think for a second these players aren't getting their collective asses busted by this staff. My brother in law was the corches clinic this spring and said he can tell you first hand that reports of Antonio Coleman walking off the field, are for real. He said Rocker had them running this killer drill over and over and over and CTR was all up in their grills. Finally, after AC had run it for about the 6th straight time, he told Rocker where to stick his drill and practice and all this shit...and walked off.
He walked back on obviously, but my brother in law said Rocker was killing the D-linemen.
