The 49ers play the Broncos tonight in preseason action and I expect Clayton to get some significant playing time since he is battling for the position of back-up running back. How will he do behind a "real" offensive line? My prediction is if there is a defense on the field, he won't do much. He certainly won't match Darren's performance last night. I hope he proves me wrong. I would love to see him do well being on my favorite NFL team but I'm going off of what I saw while he played here.
