To be completely honest, before this past season I wouldn't have cared if we lost him. While I still think he lacks shiftiness for his size and an inability to break tackles and hit the open space from the handoff, he did impress this season when he gets the ball already in the open field. He was a big part of what the team accomplished so Cook and/or another guy are going to need to perform those tasks. The Vikings weren't going to make him the featured back like he wants. If SF wants to try that's fine, but I think they'll also find out that handing him the ball isn't his greatest strength.
