I would play Hunter ONLY if Gore does not play, it is too soon to tell if he will start or not, I'm betting he will. I like the matchup if Hunter starts, Philly isn't good vs. the run, they haven't proved they could stop it so far.
I sort of like Lloyd's matchup because the Packers pass defense is awful, but he is nursing an injury and I haven't seen anything from him that shows he wasn't a fluke last season.
I don't like Greene's matchup, he hasn't been able to run the ball effectively yet this year and the Ravens D doesn't allow for much running room either. He might get a TD but I see a low scoring affair in this one.
If Gore plays, I'd go with Lloyd or a FA option. If he doesn't, take a risk and play Hunter.
What options are there in FA? On a side note, is that Clinton Portis on your roster? If it is drop him!
