I don't see why the Jets, if they really wanted to for some dumb reason, couldn't run the spread option too with the same results. With Greene and McKnight and Sanchez they could run the ball 65% of the time too and eat up lots more clock time, not turn the ball over, and score 13-19 points a game, at most, against an average defense and maybe a few more against a terrible one. They don't need Tebow to do that.
The only difference would be the difference in size between Tebow and Sanchez, so Mark would probably get hurt pretty quickly, which will probably eventually happen to Tebow too.
The point isn't that teams can't run the spread option, its that they choose not to because it doesn't work that well. If Tebow could actually keep the offense on the field and score more than one TD per game, he wouldn't need this "magic" at the end of the game.
Take a look at the Chargers game, not only did the Chargers just completely blow the game all over the place, but Tebow couldn't do jack crap in OT save one run. All their yardage was from McGahee and because of the missed FG by the Chargers. But somehow that is clutch?
