I'm starting BJGE, but only because I have really bad options.
I'm expecting middle-of-the-pack RB3-like-stats. If he had a good week at practice, he will be the starter and will get the most carries. If Morris starts, BJGE had a bad week of practice, and will have limited carries in the game, unless Morris just lays an egg.
Woodhead will be their RB in shotgun plays, splitting that time with Edelman (who I wouldn't be surprised to see get a few carries).
I'd say BJGE gets 13-18 carries, ~50-70yds, 1Td. Won't be surprised if they are lower, though. I'd almost guarantee the 1TD.
