I would be all for bringing in parcells as an advisor. But Sanchez is fried.
However, to your point, and given the Sanchez contract, he will be around for another season. But I do not believe in giving Sanchez the starting job like in years past. He should participate in a straight up QB competition once and for all, let the chips fall where they may. May the best man win.
He won't prevail. If the Jets are smart, they'll bring in some established veteran. That veteran will surely steal the starting job from Sanchez.
