Malzahn yes. Not as sure about Pinkel. He has a pattern not totally dissimilar from what Shula had at Bama. He has a couple of mediocre to bad seasons followed by a good year or two then back again. His system seems to take a while to learn with some of it having to be OJT.It's less about the W-L record than what we looked like most of the year while losing - blown out too many times while looking completely impotent on offense and almost as bad as under Sal on defense. Also, I'm convinced that if Malzahn walked into the exact same roster CBJ found here at UT he would have won more games with the exact same players (since you bring up Mizzou their coach would have probably done better as well). That's what the issue is - some of us us feel that our talent level was not as poor as the performances we saw on the field and that the coaches did not use what talent they had properly (and therefore there is suspicion that even when we do load up with better talent how much better are we really going to be if the quality of coaching does not improve).
I have little doubt that Malzahn would have a) hired a top shelf DC and b) found a way to win 6-8 games.
