"Tebow at least won a game in the post season to get there."
Here's what's confusing. John Fox traded Tebow for Manning, and yet he doesn't trust Manning as much as Tebow. Why trade a young mobile QB for an aging QB who was injured for a year and will be retiring soon, instead of spending the money on improving the defense, if you don't even trust him?
As the QB of the Broncos, Tebow was trusted to throw deep for a single pass play, leading to a win in OT.
The next year, as QB of the Broncos, Manning went 0 for 4 (or so) possible attempts in the last 30 seconds to fight for a win, eventually losing in OT.
Heck, in three other famous games, Brady moved the ball to field-goal range to break a late fourth quarter tie with just a few seconds on the clock each time. (Yes, earning his three Super Bowl rings.)
Maybe John Fox thought that Denver would win the coin toss again? (Tebow did what Manning could not there, too.)
