So far, all signs are positive (even though that doesn't tell us too much just yet). He's one of the many high risk/high reward RBs out there this year. Keep in mind that his value will be higher in leagues with playoffs, since he may need some time (about half the season?) to return to pre-injury form. He'd be a great back to have on your bench if he slips in the draft, but you shouldn't put yourself in a position where you're dependent on his production week in and week out.
