Week 10 vs. Dallas
Charles Sims actually played more offensive snaps last week (32) than Doug Martin (31). It was close, but that stat just emphasizes how much of a role Sims has in Tampa Bay's offense. For what it's worth, he finished with 82 total yards.
Martin is still the lead back in Tampa, but you can't deny Sims' impact. He'll continue to get touches, and will do so this week in a favorable matchup against Dallas. Sims isn't a strong option, but he should be viewed as a solid RB3 or flex play in Week 10.
