Tebow is like what happened when Miami brought out the Wildcat offense a few years ago. For about a season and a half it was effective because defenses didn't know what to do with it. When they learned it stopped being effective and became something that gets used once or twice a game rather than as a full offensive scheme. Tebow presents problems short term because nobody has seen enough of him to drill their defense on how to stop what he does. By week 1 of next season he's history because everybody is going to know how to take him out.
I've been thinking along similar lines, although I think it won't take nearly that long for teams to figure out the defense.
I haven't followed Tebow as closely as others, we don't always get Denver down here in NC. But what I have seen is that he has helped win in the games comming from behind in the late 4th quarter. That's when the other team is running a prevent defense. Tebow's unusual style is perfect for scoring on the prevent defense.
In the prevent, you have a minimal rush. Tebow, while not the fastest QB can get away from D linemen. Then the secondary is deep down field trying to keep everything in front of them. This gives Tebow plenty of room to take off running. And, as we saw last night, Tebow is so big and strong he can break tackles by DB's.
IMO, this is an easy fix, and one I have seen before. All that a defense need to do to adjust is set up an OLB type (faster LB with good lateral speed) as a 'spy' on Tebow. The Panthers used OLB Davis as a spy on Vick and smoked the Falcons back when Vick was really running well.
Tebow's passing is horrible. He's really inaccurate. The only reason he hasn't had a bunch of interceptions is because he often throws far too short/low where nobody, including his own receiver, can catch it. Throwing balls so completely uncatchable is hardly a positive. And if he keeps that up some team will run a LB or DB underneath in (a zone type) coverage to snag those.
Tebow's big advantage now is his uniqueness. I don't recall many, if any, QB's who were built like, and run like, a fullback. I noticed Reeves didn't want to challenge Tebow on that sideline in the last drive, or maybe he expected Tebow to slide or run out of bounds. Teams are going to adjust to this, and treat him like a FB going for the extra yards instead of just a QB scrambling. He's going to get hammered eventually. We'll see if he can take it.
And as has been noted, if Denver gets behind by several TD's Tebow's just won't be able to catch up.
Somebody above said something about people not crediting a strong running game enough. Well, IMO, if you can't throw the ball the other teams are just going to stack the box etc. They can also put LB-sized safeties (or smaller faster LB's) to bring the wood. It's just too easy to game plan for a one dimensional team
