Tim Tebow could be about to pass second-year QB Tom Brandstater on the Broncos depth chart according to Mike Klis of the Denver Post. Tebow was the third quarterback in during the Broncos’ first offensive play series Thursday. Returning starter Kyle Orton took plenty of reps with the No. 1 unit and Brady Quinn got his reps at No. 2. And then Tebow went in for a few plays, followed by Brandstater. On the next drill, however, Tebow was the fourth QB to take reps. Brandstater was third. Source: Denver Post
