"And so with me coming to Denver, I've been completely blessed in being put in such a great situation. This has been a huge year for me. And I'm extremely happy with where I'm at."

Osweiler didn't throw overhand all the time at ASU, sometimes dropping his right elbow below his shoulder and winging it out a bit, which negated his height advantage over the Pac-12's pass-rushers.

So, after deciding to forgo his senior season in a new system under a new coaching staff, he went to work last spring with UCLA offensive coordinator Noel Mazzone, who was his offensive coordinator in college, to fix flaws in his passing game.

His education really ramped up when he started dissecting Manning's every move.

"I've learned so many things this football season that I wouldn't have if I'd stayed in school," said Osweiler, adding that deep down, he's sure "it's a situation I think a lot of quarterbacks would do almost anything to have. I recognize that and that's why I try to soak it up every day."
