I disagree on several levels.
* tebow is a winner in the Urban Meyer system. Lotsa reasonably athletic kids could, did, and will succeed in that system. It really doesn't take much pure QB talent to do so. Kicker: NFL teams (so far) don't run Urban Myers' system.
* McDaniel is unproven as a QB/player development guy. He had some success as an OC @ New England, but the scheme was already in place and so were the players. Not hard to look sharp with T Brady working a gameplan that he knows by heart, with W Welker and others in support.
* I'd bet straight money that Orton will start in Denver this season. Quinn is a bust, just like almost every other neuter dumb QB in the modern era. Maybe tebow will compete in year two or three, but I see him converted to something else.
YMMV, of course; this is fun because it's all opinion.
Cheers!
