The official website of the Buccaneers lays out a scenario where rookie Charles Sims will take "a handful of carries in [Doug Martin's] place and perhaps also (serve) as the third-down back."
This gels with what coach Lovie Smith said about Sims earlier this month, complimenting his hands and saying he "gives us a little more in the passing game than what we've had."
Sims caught 45 passes for 401 yards and three touchdowns at West Virginia last season.
