Both schools of thought are right. CTT was not the end all be all that Kaos makes him out to be (he acknowledges that) but mostly comes on defend him against those that were in love with him and now consider him Terry Bowden esque in his tenure. Bottom line was that he brought us out of one of the worst coaching hires (outside of Barfield) and made our program relevant again.
His attrition rates for keeping players the last few years was bad, we had some really bad blow-out losses, he was very conservative. He had a tendency to be loyal (bad?)
He also won 6 Iron Bowls in a row and coached an Auburn team that could be considered one of the best in history. He had an 85-40 record (68%...Dye had a 71% WR), took us to a bowl game 8 out of the 10 years, winning 5. He graduated players.
I would say he did pretty much everything we asked of him. It was time for him to move on, and he did. I wish him well, he should always be in our books as a coach. I don't wish him ill and I really don't care about Texas Tech.
Other than that we have a new coach. Here is a picture of him:
