I would play Freeman and Price.
Bruce is still nice to have, but until Warner finds his groove again, I wouldnt count on him.
Same goes with Chambers, KC may have the worst pass defense, but Chambers hasnt done a lot this year. Its just to risky to start him when you have such calibers at WR.
3rd option would be Stallworth...I see him doing a lot of good things again, but I just think Price and Freeman will be better.
