I agree with Fezz, the time to take Denver was LAST week, when the power rankings supported it. Same thing with NE: the power rankings supported taking them at home vs KC, not on the road laying almost the same line.
Carolina has an awesome OL, a better defense and running game than both Pittsburgh and New England.
They also don't have to play on Denver's turf.
Only thing that worries me is the fact that they did blow out two really good teams, and it's hard to keep up those type of performances.
