Last week it was Doug Martin that caught our eye. This week, a different running back stood out. While Martin and Charles Sims were used often in the screen game, Bobby Rainey ran a few of the deeper routes out of the backfield. Rainey, Martin and Sims are all battling to be the Bucs’ No. 1 running back, and Rainey’s ability to catch the ball out of the backfield is helping his case.
Rainey was by far the best Bucs running back last season, averaging 4.3 YPC, while Martin (3.7 YPC) and Sims (2.8) struggled mightily. Rainey also led the backs in receptions with 33 for 315 yards and a touchdown. He hasn't been discussed much this preseason as the focus has been on Martin and Sims, but he's a player to have on speed dial if either player suffers an injury.
