KC wins by a touchdown or more.
Denver, and more specifically, Plumber, have not impressed me. Plumber makes tons of bad decisions, and is easily rattled. If Portis is out, look out.
Denver has played a schedule of cupcakes this year and is taking a HUGE step up in quality this week. KC on the other hand has played a couple of decent teams and come out on top. I think this is KC's year. Their defense looks solid.
