I'm hoping the coaches noticed the difference in production between McCoy on the last drive and the one before with Karlos carrying the rock. Even though Karlos is HUGE, him running into a stacked line, he can't get it done. Put McCoy in late and let him do what he do. Run Karlos in relief and in the 3rd and 4th Qs to wear them down and then let Shifty McCoy finish it off like he did last night.
