Why is Joe Mixon under appreciated?

Don't mistake my defense of JM in this thread to be an indicator I don't want him replaced. It's just I think he brings more to the team than given credit for by some. As mentioned earlier I give a bell cow credit especially when he's averaging over 4 YPC. Although I question his character it appears the team loves him and he's a great locker-room guy. and extra 1/2 YPC doesn't necessarily make up for that.
