Any chance QB Carr plays as a rookie?

If you were told prior to the offseason that the Oakland Raiders had selected QB Derek Carr with the 36th overall pick in the draft, you may well have assumed that he would be under center for the first snap of their regular-season opener. Before they drafted Carr, though, the Raiders shipped a sixth-round pick to the Houston Texans to acquire QB Matt Schaub. Now, Schaub is slated to start in Week 1 and likely for the entire 2014 season.
