Ryan has a lot more potential as a RB than JK and I loved JK's play. FTR I think they wasted a bit of JK's talent in GB by McCarthy himself because when they came off their SB win and were still a dominant team they got beat by the Giants that could rush 4 drop 7 and I don't believe he utilized JK as a dump off or max protect package enough. But that is just my opinion so hopefully McCarthy lets Nall run and catch the ball.
