We just posted a news item today that said it was possible the Broncos would roll with Siemian and Paxton Lynch as their top-two QBs this season, leaving Mark Sanchez's roster spot up in the air. Sanchez would count $4.5 million against the salary cap, and the Broncos don't have to surrender a conditional draft pick to the Philadelphia Eagles if Sanchez is not on the roster to open the season.
As for Siemian, he doesn't have any game experience but certainly has the weapons on offense to work with in Demaryius Thomas and Emmanuel Sanders at wide receiver. In the preseason, Siemian has completed 27 of 43 passes for 285 yards (6.63 YPA). He looked confident and comfortable running the offense this past weekend, according to reports. He's a low-end starter playing in a good situation, but the Broncos may end up taking a run-first approach with C.J. Anderson, and what is a competitive battle for the RB spots behind him.
