My family has had Jets season tickets since the late 60's. I have been going to games every sunday (or watching away games) religiously since I was a little kid. And, I can tell you, I have never seen anything more stupid then Jets fans reacting toward Tebow. They thing he is a good player (he isn't) and I am not saying Sanchez was great this year, however, when he made a simple mistake that even some of the great quarterbacks in the league would make, the fans booed him and called for Tebow.
Furthermore, Woody Johnson was perhaps too vocal about wanting Tebow to get under center more than he was while Rex Ryan disagreed with that notion. I am not saying that Sanchez was great this year at all. But, what I am saying is that things like this really did mess with his headspace a lot.
