In this situation, though, McD almost has to show he didn't screw up by drafting Tebow. He's been getting called out big time for his personnel decisions and needs to respond. It's not like they spent some 6th round flyer on a guy with an outside chance at panning out... if you valued him as a first rounder, he should be a lot more "player" than "project".
Of course, McD is going to hold off playing Tebow this year as long as he can. Why? Because he's got nothing to gain by playing Tebow. If Tebow plays poorly, McD is pretty much dead in the water. If Tebow plays well, it could hurt Orton's value by making him appear more of a product of the system.
We're all set up to make this move. Quinn is a waste of a roster spot as long as Orton is on the team. There's no question that Tebow wants to start. Orton isn't a clutch player, despite his stats.
I'll be surprised if Orton is still on the roster next fall.
