No one's "cheering" for us to lose in order to accomplish their "self-serving" desire to be rid of Christensen. This is simply the expression of optimism about a greater future in the face of an ugly reality. Besides, even if people were willing to see us lose a few games to try to move the program forward, I'd say those are people displaying a willingness to sacrifice for a greater good than those who would advocate the comfort of status quo mediocrity.
The people who "want us to win with Christensen" are part of the same mentality as misguided religious zealots who feel modern medicine is an affront to their faith- people willing to allow their own children to suffer in order to keep their "faith". The plane has hit the mountainside. Faith isn't going to get it back in the air.
As for the program sustaining mediocrity, sorry, but the world of College Football is in a time of great flux. Programs that cannot compete will be culled from the herd as time goes on. Mediocre teams like Wyoming will find their FBS/ D1 status under severe threat, and if Wyoming football was forced to drop a level (whether its a new one sprung from the current FBS iteration, or an outright move to the FCS) it would be the end of the program's support from serious donors.
Personally, I believe Christensen will get the axe following the seventh loss of this season. If a seventh loss doesn't happen, we're likely to see him again next season barring a new AD deciding to conduct a full evaluation and review of his tenure thus far and deciding that all things being what they are, excellence just isn't in the man's DNA.
Personally, I'll be cheering for Wyoming in the next three games, cheering for them to win against Hawaii, Boise State, and Utah State. I will back to team as a whole. However, I will also look for a silver lining in any losses- that being the very limited future of Dave Christensen at the University of Wyoming.
