Not to single you out, but I think funny that the same people who will not give Mac Jones the slightest benefit of the doubt for having horrible coaching, bad offensive line, a lot of injuries, no true #1 WR, etc. make similar excuses for Tom Brady.
Why is it so hard to accept that Brady is 45 years old and he finally starting to lose the battle with Father Time? Last night, nothing you said that was working against him was the reason when he tried to throw the ball out of the back of the end zone, it went right in a defender's hands. Again, I have only watched 4-5 games and in those games, he has shown a clear deterioration of the accuracy of his passes on a lot of plays. And if you take away the Carolina game, there is a clear decline in his play over the course of the season which is another sign of age.
Brady of five years ago would have overcome all the things you listed and played well.
And he looked better in the second half in large part because it was garbage time. The score was already 24-0 when he had his first TD drive. It was 31-6 in the fourth quarter when he had his second and last TD drive.
People want to talk about how horrible of a OC Leftwich is, but Jameis Freakin Winston had 5109 passing yards and 33 TD with Leftwich calling plays. Winston is a turnover machine. So he also had 30 INTs.
