Him and Reid did not use McCoy enough a lot of times and Marty is and will always be a pass happy OC but thus far he's done a great job of utilizing the run. Might have been Rex Ryan who wanted to run it up the gut vs New England late in that game given the DTs were gone for NE. Philly fans I think hated the pass happy offenses of his.
I read some where that mm left reid because reid wanted to call the offensive plays again and mm didn't want give that up.
