GAME PREVIEW: KC AT BUF — WHEN TWO GOOD OFFENSES MEET

Josh Allen's EPA/play is not a fluke. He's the third-most efficient offensive quarterback in the league by this metric through Week 10, and it's held across three different offensive coordinator regimes. Buffalo converts drives into touchdowns at 37.1% — the second-best rate in football. If BUF's drives look this efficient against a decent KC defense, those aren't garbage-time numbers piling up.

The counterpoint: Patrick Mahomes compresses variance. Kansas City's EPA number is lower, but their third-down conversion rate is one of the league's best. They lose fewer drives to punts than their EPA suggests because Mahomes manufactures first downs at a rate the aggregate doesn't fully capture. Their TD% is low because they take more field goals — not because they can't move the ball.

1. FIRST-DRIVE TEMPO. BUF's opening drives have been some of the highest-EPA possessions in the league this season. KC turns the ball over on first possessions at a higher rate than expected. If BUF scores on the opening drive, the win probability shifts 8–10 points.

2. KC 3RD-DOWN EFFICIENCY. Mahomes at 42% on third down vs. BUF's 36% allowed is the most interesting number in this game. If KC converts 3rd downs at their season rate, they generate enough drives to stay in it despite the EPA disadvantage. If BUF's defense holds them under 35%, KC's offense doesn't have enough volume to produce.

3. DRIVE TD% DIFFERENTIAL. BUF converts drives to touchdowns at a rate ~15 points above KC. If both offenses match their season averages on scoring efficiency, the Bills are projected to outscore the Chiefs by roughly a field goal on equivalent drive volume.
