Ultimately, that's the part that's causing so much of an issue here. Both sides are selfish, and should be.
The coaches and fans want to have a player of Gebbia's capabilities as a backup. To say any different would be a lie. But it is selfish.
Gebbia wants to be a starter, which was never going to happen here outside of an injury. While we're in the future, that's a lot to bank your collegiate and possible professional career on. He needed to put himself in the best position to be a starter, and that was not at NU after Coach Frost said the only reason he isn't the starter is due to Martinez being a little more mobile (or something to that effect, I don't care enough to look up the exact quote but they were essentially tied). This is selfish.
Coach Frost took 2 players of equal skill (neck and neck?) and used fit as a tie breaker. Martinez fit the scheme more than Gebbia. It's telling he went to Oregon State and not another RPO/Zone read school. He is a pro-QB that worked his a$$ off to play here. It didn't work out.
What is crap, however, is that Gebbia should be selfess to serve the selfish needs of fans and coaches. And that's what I take offense to. That long time members are disparaging him (just look through this thread around the time Martinez got hurt, it's horrifying). I lost a lot of respect for many members of the board today.
