(BetMGM/WGR Sports Radio 550) - The Buffalo Bills and Kansas City Chiefs have faced each other eight times in which their respective starting quarterbacks were Josh Allen and Patrick Mahomes. They’ve split each of the matchups to this point.
How do the two quarterbacks compare overall on the moneyline over their careers?
Mahomes’ regular season and postseason moneyline Return on Investment (ROI) of 16.5% ranks second among all quarterbacks since 2018 (min. 50 starts). Ryan Tannehill is first (24%), and Allen is third (11.9%).
In just the postseason, Mahomes (16-3) ranks third (38.4%) among quarterbacks with, at least, five starts. Allen’s seven postseason wins are third behind only Mahomes and Tom Brady (8), but his ROI of -16% is eighth. Five of Allen’s wins have come when the Bills were a favorite of, at least, -200.
Nearly 90% of Mahomes’ starts have come as a favorite. And barring late line movement in BetMGM’s AFC Championship odds, he’ll be a favorite against the Bills on Sunday. The Chiefs have won 81% of those games for an ROI of 9.9%.
About 30% of Allen’s starts have come as an underdog. The Bills have won only 44% of those games, but have an ROI of 24.6%.
In all home games, Mahomes is 54-13, though that’s translated to an ROI of just 5.4% thanks, in part, to 39 games as a favorite of, at least, -300. In all away games, Allen is 32-24 with an ROI of 11.4%.
