In his return from a knee injury Week 4 at Pittsburgh, Buccaneers running back Doug Martin led the way with 14 carries. The second-most went to the player who thrived in his absence, Bobby Rainey. He got only four.

That's mostly good news in Fantasy, but for the Rainey owners, perhaps it isn't. Certainly, you'd rather see one of the two backs carry the load rather than another timeshare, but maybe Martin isn't the one to do it. He scored a touchdown, sure, but he gained only 40 yards on those 14 carries, giving him 2.1 yards per carry on the year.

Rainey, by comparison, is averaging 4.9 yards per carry. True, he owes much of that to the 144 yards he had on 22 carries against the Rams in Week 2, but despite the two early fumbles Week 3 at Atlanta, he still finished with 105 total yards in that game, 64 on the receiving end.

Ideally, if you own Martin, you own Rainey and vice versa. Whichever gets the carries looks like he'll get the vast majority of them. But I still have some doubts as to which running back will emerge in the long run.
