With that said, Cro has been lights out this year!! Rex is great on the Defensive side he's just lacking talent at some positions due to age and so forth. If you O was able to sustain a few drives and give the D some rest time no doubt this team would be exponentially better. Look @ 2009 and 2010 for example.
With that said your RunD has been on a down but I think some of that is attributed to being on the field too much during spans of the game.
