This Woody Paige article is absolutely worth your time. Paige has the ultimate insiders view of the Tim Tebow situation at Dove Valley (and beyond).
I have now talked to at least a dozen ex- and current coaches (Dan Reeves and Jim Fassel and Bratkowski, a former long-time assistant, and Boyd Dowler, who played for the Packers and coached and scouted in the NFL for years and others off the record because they asked that their names not be used, but they are former quarterbacks), and not in any discussion did I know going in what they thought of Tebow, and I didn’t push them for positive responses about him, and I was stunned that every one of them thinks he will be a great NFL quarterback. - Woody Paige (Denver Post)
