I don't think it's so much about "pulling your head out", which to me implies a lack of intelligence (maybe you mean it in a different way), as it is about looking at the situation with a modicum of objectivity. (For me, the truth is Leach was <10% of the problem - but was part of it - and the admin and GOB guys who made it happen were >90% of the problem.)
Instead, most Tech fans' reactions landed closer to the two extremes of either "he fucked over my school so fuck him" or "Tech fired my coach so fuck Texas Tech for all of eternity! I hope Tech never wins another football game!" And that's because too many Tech fans are thin skinned and hypersensitive and tend to quickly circle the wagons to defend their position as soon as things get difficult. We're probably not the only fanbase like this, but we're collectively definitely like this.
The saddest part of all this - besides, of course, the last decade of shit football we've been served up - is that while the GOBs back in the '00s definitely got scared that the football program would start to get too big for them to control anymore, the current GOBs are ready to pay a fortune to get us back where we were as of 2009. Maybe they wouldn't be so determined if football hasn't been so bad for so long (with all the negatives that come along with being bad at football, besides just watching the futility on the field), but it just sucks that we had a coincidence of petty, small minded leadership at the same time that we could have invested in the future and built on 2008 instead of blowing it all up.
