He had Davis coming wide open in the end zone. No way he can see the defender diving at his legs while trying to throw the ball. Just like the throw to Davis earlier it's a split sec between a completion and a turnover.
I can't imagine with the probability of a game being played before the makeup game that they could enforce the rosters. So much could happen between with players going down next week that you would then be compromised at additional spots. Would only make sense if it was played within a day or 2 of original date.
Not when it's clear view he has the ball, on the ground and the defender reaches in and pulls it between his legs. Had it been a pileup and you can't see it sure, but in clear site it's down by contact.
He may be off a little, but rarely is it an uncatchable ball. The rest of the offense has to make a play sometimes. We see every other team make plays against our DBs with good coverage.
Here's a stat that hasn't been mentioned from what I've seen. Mahomes has thrown a game ending INT in 3 of his last 7 games. He's good, but that is far from "Best QB" type play.
