McFadden, Rainey, and CJ2K are probably the best options available. I'd imagine De'Veon Smith will be promoted from practice squad.
Gotta be some free agents out there, D.H Harris, Smash Williams, J.J. Pryor, Julian Washington would be nice, maybe see if Megget is healthy?
Trade Deadline has passed. That said, I'd be all over Crowell for the right price to pair with one of the guys we have now. Right now, we probably just promote from the PS.
Honestly, I'd move Landry to RB for a game. We use him as a running back anyway, why not make it official and let him dance in the backfield some? That sucks for Williams though- it looked like a dislocated shoulder as he hit. Those can be anywhere from not a big deal to a huge rehab, so we need to cross our fingers there.
Yes, I wondered if it was a broken collar bone when he hit. Lucky it's not, so there's a chance he can get back sooner. Not that it really matters a whole lot, but for him and his career, this was a good chance to build his resumé a bit.
