Yeah, all Utah State fans certainly don't feel that way, but your message boards definitely have given off that vibe for a few years now. I mean, c'mon, you guys were the impetus for the so called "Riley Nelson" rule that the NCAA passed.
As for Heaps, I don't know. Best case scenario for BYU would be that Riley Nelson continues to play well this year, goes into next year as the starter, and Heaps takes a redshirt year to foment some kind of passion and learn to put some touch on the ball. He's too mechanical for anything other than looking like an All-American in practice right now. Although, certainly the guys calling the plays haven't used him properly. Of course, like you mentioned, there is a high probability that he is a primmadonna and won't want to take the lesson and learn from it and come back and compete for the starting job in '13.
Ben Olson was the #1 rated QB a few years back coming out of high school, transferred to UCLA from BYU after the coaches played games with him, and bombed out so I wouldn't even flinch if he left other than possibly be concerned about future depth. BYU's got some nice QB talent in the pipeline, I'm not sure he is a lock to come back in '13 and win the starting job if that's how this situation ultimately plays out.
