Ok, those of you accusing Gabbert of pulling a Josh Freeman are ridiculous. Gabbert decommited in the midst of Bill Callahan's regime collapsing on itself. He wanted to play in a pro-style offense to groom him better for the NFL. He decommitted publicly LOOOOOONG before signing day, not sending a text message just before, when it looked like Callahan was solidly the coach of the team for years to come.
As for the recruiting question, it isn't dirty at all. He was doing it when he was a Husker, and now he's doing it because he wants to win games. Also, you guys sure didn't mind it when he was doing it for you:
