With training camps starting this weekend, and preseason games just around the corner, it's time to look at some key job battles to gain clarity so we can dominate our fantasy drafts.
Robert Griffin III handled most of the first-team reps throughout the offseason, but if Griffin has difficulties running new head coach Hue Jackson's offense, Josh McCown showed last season that he still has the ability to move an NFL offense well. Jackson said he'll name the starting quarterback before the team's first preseason game Aug. 12.
General manager John Elway said this week the quarterback job will be an open competition in training camp. Mark Sanchez is the No. 1 QB entering camp, but he'll share first-team reps with Trevor Siemian. First-round draft choice, Paxton Lynch, struggled during OTAs and seems unlikely to overtake his competitors during preseason.

Case Keenum is the incumbent but had plenty of struggles leading the Rams offense in 2015, and the team used the first pick in this year's draft to select Jared Goff. If Goff can show he's ready to make the team competitive, he could easily push Keenum into a backup role as early as Week 1. Helping the rookie's case is that coach Jeff Fisher said he was impressed with Goff's preparation this offseason.
