Sanchez proved he could make big plays when he had a solid supporting cast around him. Let's not forget some of those big plays he made late in games over the 2010 season that were the difference between L's and W's. Key words being: Supporting cast. Look back at the same period when Sanchez was making those plays, Alex Smith had no one protecting him and he looked just as bad as Sanchez did this season.
I do agree that Smith is better, but I think if you had him under center for the Jets this year instead of Sanchez -- he would have looked almost as bad.
Game managers are a product of their environment.
No one remembers who came in second.
