I don't think this question needs to be asked at all. The football program is trying to rebuild.
1. ACS had become a rock star his first year, player of the year, etc.
2. Team captain the second year.
3. High/unrealistic expectations placed upon him by the media and the fans.
4. Coaching staff realizes the intense pressure, shuts down practices to the fans and media, and take the brunt of it themselves.
5. 3 win season.
The guy probably wanted to play some football, get an education, and have some fun along the way. Instead, the media was always beating up on him, the fan's don't seem to have much confidence in a second year coach, and he probably walked away feeling like he had sunk the program. The media certainly doesn't help - they'll do anything to publish a little drama.
I'd say the media, the internet, and the 24 hour news always trying to get a story are probably some of the biggest challenges the football team has to face these days. This stuff was nearly non-existant at Wyoming prior to the turn of the millennium.
It really would be alot of pressure for an 18-23 year old.
