I haven't had a chance to rewatch the game, but my impression from the stands was that Mike Shaw barely saw the field when Denard was in, but was at least 50/50 if not the primary back once Forcier came in. Any coach types have any insight on that? My casual guess would be that it must have something to do with blocking on the designed QB runs. Is Smith that much better as a lead blocker on those plays? Obviously the straight QB runs are going to be much less frequent when Tate is in.
