I play mostly dynasty, but Ryan Grant is one of those guys that can make or break a redraft team. You had to get him early if you liked him, so you have a sizeable investment if you drafted him. Anyway, not sure Grant is a difference-maker, & essentially, that's what a good RB is. I see a size/speed guy with little wiggle. Normally, those type of RBs make it only if they have good vision, & that's what I'm concerned about.
I've never seen a RB have bigger holes to run thru on a more consistent basis than Grant had last year. Whether it was the OL playing above their heads, or the Favre factor, or something else, Grant took advantage of the situation. This year, without good OL play, & Ds maybe playing them a little different, he's struggled. Could be a combination of those two things & his hammy. Or maybe Grant doesn't have the vision to excel over the long-haul. Color me leery, but I wouldn't say he can't do it (at least not yet).
