He needs to be literally perfect, and that's infuriating. He passed up the Diggs crosser on 2nd and 9 because the TD to Shakir was there. You can't pass that up in that moment, regardless of what Mahomes might do. Tom Brady wouldn't have passed that up. It missed by a fraction of a second due to Jones bullrushing Dawkins into his back.
He played nearly flawlessly, a goddamned superstar in the biggest game of his career. I've never seen another great player forced to be perfect game after game for such a sustained period. It's outrageous that he'd be considered anything other than great.
