The Patriots emasculated and embarrassed Jones in the Bils game last year and he hasn't been the same since. When the team has so little faith in you that they refuse to throw the ball, it is devastating for your confidence especially as a rookie.
What a dumb hot take.
Have you looked at the numbers?
In the 12 games before that game Mac's main numbers
70.34%, 16 TD's, 8 INT's, with a 97.1 passer rating and the Patriots were 8-4.
In the 4 regular season games after the Bills game
59.85%, 6 Td's, 5 INT's with a 79.7 passer rating and the Patriots were 1-3 (and the 1 which was a 3 TD/0 INT game was the awful post-Meyer Jaguars when the Pats scored 50).
In the playoff game
63.16%, 2 TD's, 2 INT's with a 75.8 passer rating
Thus far this season
65.98%, 2 TD's, 5 INT's with a 76.2 passer rating and the Patriots are 1-2
The simple reality is, since the Patriots threw the ball 3 times against the Bills, Mac Jones has looked like an entirely different QB and the team went from winning 2 out of 3 games to winning just 1 in 4 games. Now sure maybe that is just a coincidence and has absolutely no correlation at all, or maybe just maybe embarrassing your QB on national tv might not be the thing to do.
