NFL.com's Steve Wyche has done some reporting and thinks that the Broncos starting QB job is Tim Tebow's to lose.
ProFootballTalk did the transcribing of Wyche's podcast and the major conclusion was this: "I have talked to enough people . . . to comfortably say that unless Tim Tebow gets hurt in training camp or is absolutely awful, the starting job is his to lose. They want to find out if Tebow can play."
