In response to Paul_K's comment:
If Tebow gets cut, Buffalo picks him up. They're pretty desperate. Tebow would play pretty tough against the Patriots (well, tougher than normal for him) and Tebow works cheap these days.
Tebow has a good chance of making the 53 cut, with all sorts of players getting stashed on injured reserve. He'd have to blow it on the plays where BB ordered him to play well. The rest of us don't know which plays those are.
Giants coach Coughlin is from the Parcells / Belichick coaching tree. Both coaches will be highly interested in losing this preseason game, so it could get wacky on fourth down. Don't expect Tebow to pull miracles when the coach directly told him to throw the ball either into the dirt or straight at the linebacker's numbers.
Wait wouldn't that be a good reason to cut him? Heck, maybe we'll be lucky enough that after a bad week 1 start the Bills would cut him and the Jets would pick him up. The only 2 times he faced the Pats as a starter he lost 41-23 (garbage time TD) and 45-10. Why wouldn't we want to face him?
