Bills Injury Report

Patrick Mahomes enters Week 9 as the betting favorite to win his third NFL MVP award. He has been phenomenal this season, showing flashes of his younger self. He has completed 67% of passes for 2,099 yards, which is an average of 262.4 passing yards per game, along with 17 touchdowns and only four interceptions. He has also used his legs more than he has in recent years, racking up 280 yards on the ground along with four touchdowns.

In this week’s edition of the Road to 272 Bets, I broke down why I’m backing the Chiefs to win and cover as short favorites in Buffalo:

The Bills’ offense remains one of the best in the NFL, but their defense has struggled. They rank just 13th in opponent EPA per play and 26th in defensive DVOA. Bills fans should be scared of this year’s version of the Chiefs, which has been far better by almost every metric than they were when they went 15-2 last season. Their offense is better than it’s been in years, including ranking fifth in DVOA and fourth in EPA per play, but they are also better than the Bills defensively.

The Chiefs are a step above the Bills at this point in this season. I think they win and cover in the one-point spread in this spot.
