Bobby Rainey - Week 13 vs. Cincinnati Bengals
The Bucs' backfield practically saw an even split between its three backs. Here's the snap count breakdown: Doug Martin - 26, Charles Sims - 25, Bobby Rainey - 25. Even their combined efforts don't make a for a great back. The three combined for 52 rushing yards and 33 receiving yards for a total of 85 yards. When you split the three you just get a bunch of ineffective fantasy players.
All three players are low RB3 options. There's an off-chance one of them scores a rushing touchdown, although I wouldn't bet on it. Josh McCown still leads the team in rushing touchdowns with two.
