One big question that weighs into this is the health of Peyton Manning. Early signs are that he's going to be fine but an MRI is coming. That is the biggest thing remaining that could affect the line.
Last week I asked the guys over at Odds Shark what the line on the Chiefs-Broncos game would be. The official line wasn't up yet but our guy there polled two oddsmakers and they both said -6.5 for the Broncos. The difference between -6.5 and -8.5 is huge considering a lot of games end in a seven point difference. The Chargers lost to the Broncos by eight points last Sunday so KC would have to perform that well to have a shot at covering.
But we don't really care about covering. We care about the Chiefs winning. Their 9-0 record speaks for itself but oddsmakers clearly feel the Broncos are the better team here. Not that this should surprise anyone. We've known all along that folks think the Broncos are better. On Sunday night, we finally get to put this question to rest.
