I've WATCHED Sanchez play in those playoff games and the offense is just bogged down by his (majority of the time) horrible decision making. Sure a few times a game he'll make an amazing throw but he is very inconsistent. It's like he's thinking about what to do instead of knowing and reacting to what he sees the moment he sees it. But with that said I have nothing against Sanchize he is from my fav college team and wish him well when not playing the Cowboys, Hell I was even rooting for him to do well against pissburgh in that AFC champ game last year (i hate pissburgh).
For him to stay the Jets QB I feel like he's gonna have to excel this year, ya know, carry them in a few games, cut down those INT's and vastly improve his decision making and accuracy.
If Romo had the line that Mark has he'd put up a lot better numbers than Mark even with what Mark has had at the WR position.
I wouldn't want him as my QB!
