The ones with only 3 losses don’t have much of a sample size for this chart so one bad game will skew it. Mahomes almost certainly all comes from the Broncos game, which was his worst EPA ever in a start.

I wonder if it’s partially because (for example) a guy like Mahomes will frequently find a way to scratch out wins even if he doesn’t play great for part of the game, and so if they lose it is sometimes because he made some huge uncharacteristic mistakes or whatever

Like herbert and Allen are good QBs who just keep losing in all kinds of situations this year, good play or not. It kinda takes and particularly subpar performance for Mahomes or tua to lose the way those teams have been playing
