After rolling for 1,496 total yards and 14 touchdowns in his last season at school, Buccaneers rookie Charles Sims figures to be a key role player right away for the Bucs behind starter Doug Martin. He'll compete with Mike James and Bobby Rainey for playing time in training camp, but he's the one we'd draft as a handcuff to Doug Martin (or as a reserve rusher in deeper leagues). Sims can be found with a late-round pick in seasonal leagues, a mid- to late-round pick in dynasty/keeper leagues and a late-second to third-round choice in rookie-only drafts.
