For a 5th. Good pickup for them. He would have been a better fit in our system than Robinson due to his breakaway speed, but Robinson is a better overall RB.
I would have rathered Wilson for the breakaway speed but you made the point exactly. I've heard the condition for Robinson is a 5th if he gains 600 yds for season (or 600 yds for us? that makes more sense to me)--if we do give up a 5th then apples for apples I'd have much rathered had Wilson--if its 6th vs 5th, its breakeven longer term IMO.
