What's the cost per square foot of bench to accommodate Sanchez's salary and butt?
The guy has physical talent. He played one season of college ball and then against the advice of his coach, Pete Carroll at USC, he jumped to the NFL despite telling Pete the night before after a sit down to discuss to stay at USC or go for the draft, Pete left with the understanding that Sanchez told him he would follow Pete's advice and return to the USC. The next day Pete found out the opposite from the media.
Then Sanchez goes to one of the worse team that a young and very inexperienced QB could go to, the Jets. They promptly prove that with their first move regarding Sanchez by tossing him to the wolves as a starter. They then reinforced their decision to have him learn the game from a group of coaches and surrounding players, the former more important than the latter, that are not the group you want to backup and teach your rookie QB.
The results were predictable. Sanchez's only chance as an individual to be a successful solid NFL QB is to go to a different team. Even then he may or may not succeed. But he will never succeed with the Jets and playing in New York.
