I don't know about over rated. Well maybe a little. But I grabbed KC +4.5 yesterday. This is smack bang in the middle of 3 straight division games. They just played in a tough game, the Raiders Super Bowl, and then have to worry about travelling to DEN on a short week for a TNF game that means way more than the KC game.
Great spot for KC. Wouldnt be surprised to see +3 by kickoff.
