I don't know if anyone has mentioned this before or not, (if so - my apologies,) but now that we have Tebow, why not try something a little radical?
We all know Tebow's strengths and limitations. And also taking Sanchez out of the game when Tebow's in will only disrupt his rhythm. So...
How about having Tebow and Sanchez line up TOGETHER in the shotgun for EVERY offensive play? (During the snap count, one of them can go directly under center occasionally too.) The majority of these snaps will go to Sanchez. Tebow is strong and versatile enough to help out as an extra blocker or as a dump-off receiver option. Tebow can be like an option QB, a blocking tight end and a fullback all-in-one!
Of course, the defense will never know when the snap will go to Tebow instead. And this offense keeps both Tebow and Sanchez active and involved. No one will be sitting on the bench getting "cold". Of course, Sanchez is pretty worthless out there if he is not the QB, but again, most of the snaps will go to Sanchez anyway.
Offenses often line up with two RBs. Why not two QBs? With Tebow as the second QB, it could be a realistic possibility.
Then again, maybe I'm just crazy.
