How do Jets fans convince themselves that Mark Sanchez is a good QB when he is trash and obviously a bust?

Sanchez has done more to help is team in his first two seasons than many other QBs do in their entire careers. Calling him trash and a bust is silliness, as he obviously has talent to play the game. Busts don't get to their conference championship two years in a row. I'm a Steelers fan, and I respect what he's done for his team.
