The Bills recently worked out free agent running back Orleans Darkwa, Ian Rapoport of NFL.com tweets. Darkwa, who last played for the Giants, is now back to full health after having a plate removed from his leg. 
Because of his medical issues, Darkwa hasn’t drawn a ton of interest in free agency so far, though he did visit the Patriots in April. The Giants reportedly had some level of interest in re-signing him, but he was left out in the cold after they drafted Saquon Barkley with the No. 2 overall pick and signed veteran Jonathan Stewart. The crosstown Jets were also eyeing Darkwa at one point, but signed Isaiah Crowell and Thomas Rawls.
Darkwa, who is still only 26, ran for 751 yards off of 171 carries, giving him a 4.4 yards per carry average. It was an ugly year for the Giants on the whole, but Darkwa excelled on a personal level.
The Bills, of course, have some potential needs at running back as LeSean McCoy‘s situation lingers. Outside of McCoy, the Bills have Chris Ivory, Travaris Cadet, and Taiwan Jones, and that’s not a tremendous bunch.
Great fit in the right system
He will do well for any team that signs him.
Put up a good year with no passing game and run blocking not many backs can do that.
That’s a good point: if he could put up good numbers for that Giants team last year, he should be able to do it for just about anyone.
But we have Taiwan Jones and Cadet!
