I'm actually taking a flyer on Robinson. I don't have anything good in my last roster spot, and if he becomes the starter, you could have a RB in your WR spot. This would most likely boost your point totals significantly.
It looks like Gore is going to get carries from goal to goal, which seems to be pretty rare for a RB not taken in the 1st round. Most later round RB's are 20 to 20 guys that have goalline vultures. I think that Gore could actually put it pretty good numbers because of this.
