Indianapolis Colts (11-5) at Buffalo Bills (13-3)
The Colts qualified for the post-season at 11-5 and their 8th ranked +89 point differential is what you’d expect from an 11-win team, but they benefited from the league’s 2nd best turnover margin at +10 and the league’s easiest schedule, two things that don’t bode well for this Colts team as they head into the post-season. Turnover margins are highly inconsistent on a week-to-week basis and teams with a turnover margin of +10 or better manage just a +0.05 turnover margin in the playoffs, so the Colts won’t be able to rely on that again this week. On top of that, their strength of schedule is going up significantly, as the Bills are arguably the top team in the AFC.
The Kansas City Chiefs get a lot more attention as defending Super Bowl Champions and the AFC’s #1 seed, but it was the Bills that led the league by a wide margin with a +4.67% first down rate over expected (Kansas City finished second at +3.61%) and that lead the AFC with 31.3 points per game. Both of those hold up even when you discount the Chiefs’ last game in which they rested their key players. The Chiefs have a slight edge on defense over the Bills (+0.88% vs. +1.22%), but even with their defensive edge, Kansas City still ranks behind the Bills in schedule adjusted first down rate differential (+3.45% vs. +2.73%) and defensive performance is much less consistent week-to-week than offensive performance.
The Bills’ defense has also played a lot better in recent weeks since getting healthier, particularly with top linebacker Matt Milano back. Their improved defense, paired with a consistently dominant offense, is the primary reason why they’ve won all 6 games since their bye week, by at least 10 points each, making them just the 9th team in the last 30 seasons to win at least 6 games in a row by double digits, including the 2nd (2014 Seahawks) to carry a streak like that into the post-season, although just two of nine went on to win the Super Bowl, for what it’s worth.
Ranking 4th in schedule adjusted first down rate differential, only behind a trio of NFC teams, despite a defense that has overall ranked 25th in first down rate allowed over expected on the season at +1.22%, the Bills should be considered one of the top Super Bowl contenders going into the post-season and perhaps the favorite in the AFC if quarterback Josh Allen can continue his dominant season (I might give the Chiefs a slight edge because Mahomes is more playoff experienced).
The Colts, meanwhile, finished just 14th in the league in first down rate differential at +0.08%, once strength of schedule is taken into account, so there is a pretty big gap between these two teams. The Bills should also have some homefield advantage in this matchup, with at least some fans being allowed into the Bills’ first home playoff game since 1995. Unfortunately, we’re not getting great line value with the Bills as 6-point home favorites, as they’re not underrated anymore after 6 straight wins that weren’t all that close. My calculated line is Buffalo -7, so I’d need this line to drop to 5.5 to consider placing a bet on the Bills.
