I believe Tebow's style makes the Jets better. One thing the jets can do is run block fairly well. Greene is a solid and tough runner that would get better with Tebow's threat to run back there as well. They'll become what the Broncos were, if they're smart. The only problem is that guys like Holmes would sabotage from within. Asking him to block and have 3-5 targets per game max would not sit well with him.
Still, I think the jets have to do what suits them best, and passing ain't it. Sanchez is a sitting duck, whereas Tebow has escapability and can get positive yards on broken plays or after being hit. The Jets are a dumpster fire but I'd seriously consider getting Tebow in to start and quickly.
