I don't know if I would go as far as to say that Sanchez "sucks period" or that he has his job because the NFL wants to draw attention from Latinos.
I do think that he is far less capable as a QB than he is made out to be every time the Jets win a game. But remember, he is not the guy who heaps that kind of syrup on himself; it's the media mavens that do that.
Look, Sanchez is no longer a rookie QB. When he makes boneheaded plays, that excuse is out the window. Against the Giants, he took a sack in the end zone that was inexcusable; he had a perfectly open way to step out of the end zone - - and maybe even dump the ball for an incompletion? - - before the sack posse arrived. But he didnt'...
Mark Sanchez - - despite the protestations of his coach Rex Ryan - - is not nearly the best QB in the league and is probably not in the Top 20 at the moment. The question facing the Jets and any other GMs who might consider trading for him is this:
Has he reached - - or is he near - - his potential?
If you believe the answer is "Yes", then you would not trade a bologna sandwich for him. If you think the answer is "No", you should consider trading for him because he has some learning curve advantage over a kid coming directly out of college.
Personally, I think he has some small room for improvement but I do not think he will ever be an elite QB in the NFL.
