well, Ricky Williams is a no-brainer. Indy is not that strong on defense, he will be great again.
I also would strongly suggest sitting Garner, as Pittsburgh's steel curtain is for real, even if they got torn apart by Tom Brady...of course there is a chance that Charlie will get some yds through the air, but dont bet on any gains on the ground.
Leaves a tough decision between the last two.
Something tells me to take McAllister, but it's really tough. You could be right or wrong on it, I just like home field here, and the possibillty of Buffalo getting blown out in Minnesota, meaning less carries for Henry. But after this crazy week1, who really knows?
