McCoy needs to be a 3rd down back (mostly, only). He'd be a very expensive 1 down back.
Ivory (and Murphy?) need to slam it in there 1st and 2nd down and get to 3rd and manageable.
If McCoy wants to dance around on 3rd down to try to get the 1st, then so be it.
Dancing on 1st/2nd down is a drive killer.
other option is to put Shady in the slot sometimes
