Buffalo Bills at Kansas City Chiefs: 2020 AFC Championship Pick

Buffalo Bills (15-3) at Kansas City Chiefs (15-2)

The long awaited news has come that Patrick Mahomes will be able to play in this game and be 100%, despite being knocked out of last week’s win with a concussion. The betting public obviously likes that, shooting this line up to Kansas City -3.5, but Mahomes doesn’t solve all of the Chiefs’ problems and the Chiefs are still overpriced for a team that hasn’t covered a spread since week 8, despite winning their last 11 games started by Mahomes. 

Of those 11 wins, their last 8 have all come by 6 points or fewer, including a 5-point win over the Browns last week. The Chiefs were obviously doing better in that game before Mahomes got hurt, but they were up just 9 points as 10-point favorites when Mahomes left and that was despite a missed personal foul penalty that would have nullified a goal line fumble that became a touchback and a turnover rather than a likely Browns touchdown.

The Chiefs still have a great offense, but they haven’t been quite as dominant this season, particularly in the second half of the season, with key right tackle Mitchell Schwartz out due to injury from week 7 on, a big part of the reason why they have been failing to blow teams out in recent weeks. Overall, the Chiefs actually finished 2nd in first down rate expected this year, behind their opponents this week the Buffalo Bills, who also have the edge on the Chiefs in points per game. That is true even if you exclude the Chiefs’ meaningless week 17 loss. 

The Chiefs also have concerns on defense, where they rank 20th in first down rate over expected at +0.88%. The Bills haven’t fared well on that side of the ball either, ranking 22nd at +0.91%, but even with that they’re still ahead of the Chiefs in first down rate differential, ranking 4th at +3.39%, while the Chiefs rank 6th at +2.75%. The Bills also have played a lot better in recent weeks defensively, primarily due to improved health in their linebacking corps, leading to them winning their last 8 games straight by 17 points per game. In fact, excluding a week 10 loss in Arizona on a Hail Mary, the Bills have won 11 straight games and have won by fewer than 6 points just twice, a more impressive streak than the Chiefs’ recent streak because the Bills have blown out most of their opponents. 

The Chiefs will have the benefit of some fans in the stands in this game at home and, in a playoff atmosphere, the Chiefs could have something resembling normal home field advantage, but I have the Bills as the slightly better team and have them calculated as just 1.5-point underdogs, so we’re getting great line value, passing the key number of a field goal at Buffalo +3.5. Even if the Bills can’t pull off the road upset, I like their chances of keeping it close, as 1 in 4 of games are decided by 3 points or fewer (including 1 in 6 by exactly 3) and the Chiefs have won only half of their last 8 games by more than a field goal, with their other margins of victory being 4, 5, 6, and 6. This should be a close game either way, so I love getting more than a field goal with the Bills.
