Along the lines of the durability question of Cam running so much, I was thinking the other day on how he seems to look so fresh every week. A running back in the SEC takes much more of a beating than a quarterback for the following reason:
If you are a RB and carry it 30 times a game, you are also taking shot after shot at practice each week. With Cam, he may be carrying it 30 times a game but he never gets hit during practice. It has to make a big difference on durability and endurance.
