Adams is an animal. That having been said, I've sat almost every WR I've had that has gone against the Bears this year and lived to not regret it.
Williams is an RB2 IF* KC actually uses him. Worth noting the last time the Bolts and Chiefs met up, Hunt only had 16 carries for 48 yards and they didn't get the backs involved in the screen game much.
This is what I hate about late season re-matches in correlation to Fantasy Football. You're never sure which team will mix it up and break tendency.
edit:
Just to update on my journey. Closed out the regular season 12-2, #1 Overall Seed and a 1st round bye. But Cam is being an asshole tossing picks lately. CmC is still doing his thing but those two were worth an easy (combined) 50-60 points a week for a good stretch there in PPR. Right now it's looking shaky.
