Ok ... I kind of disagree with the Leach bashing in here.
The four years prior to his arrival the team was 9-40. He turned them into what they are now, which is not a National Title Team Contender but is a very quality club.
Prior to his arrival at Texas Tech the school had two 9 win seasons from 1977 to 1999. Two. He did that four times in his decade coaching there and never posted a losing record. In the decade since he left Texas Tech, they haven't done it (win 9 games) since him and they have posted losing records five times.
These schools he is at are not easy to win at. He is a good football coach. Flawed for sure .. but overall, he overachieves with the jobs he has had.
