After seeing the effort that Lynch is putting in this season I don't know how anyone could make this assertion. While Jackson is a good RB and a wonderful player and makes a great contribution to the team. Lynch has exceptional talent and puts in maximum effort on every play. He has the potential to be a hall of fame caliber player as a starting RB. Jackson has the potential to have a long and productive NFL career as a role player.
On a side note did you also think Frank Reich was a better QB than Jim Kelly?
