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.
This may be it for Ryan Nall who in a non caste world would easily rush for 1000 yards a season if healthy. Cowboys fullback Ryan Nall out 2-4 weeks with shoulder injury (msn.com)
