You are right that Camp doesn't have game breaking speed. Then again, none of our present running backs really do in consideration of their 40 times. Danny has the fastest in the 4.3's, West and Buck both run in the 4.5's and Camp slips in between within 4.4's. I kind of feel that no matter who is in the backfield, they will be spied out and I doubt the coverage would change much imo. Probably the biggest difference between camp and our backs is the amount of bulk they carry as Camp is pretty slender and certainly more fragile.
I just feel it is a positive way to get him more snaps and help us to get another set of fairly reliable hands on the field to help us move the ball.
