I stand by that.
I know it's comparative, but his defenses especially late in his time at Texas Tech were above average Big 12 defenses.
That said, I wouldn't expect him to have lock down defenses, nor would I expect him to need them to be able to beat the average and bad SEC teams we play.
Would we lose to the LSU's, Florida's, and Alabama's when they're great? Definitely, but we will with just about anyone we hire. Leach would likely at least give us a better than average chance at beating all of the middle of the road teams we would play and would give us a fighting chance in some of those other games.
Leach did manage to beat Eli twice, so again I think it's ridiculous to use one game as an argument against the guy.
From 2000-2009, Leach's teams had fewer NFL draft picks than we had in the same time period. He went to 10 straight bowl games, and we went to 5 during that period.
