JJSS has been awful this year. And it isn't because of Mac. And he was not so great after he got injured last year. He was awful in the Super Bowl.
Rham has been awful prior to the last two games.
Henry is good, not great.
Geisicki is on track to have a better year than he had last year which isn't great.
Trent Brown has missed three games. His replacements have been awful.
Ownenu struggled this year at guard and only really played well the last two games when he was moved to tackle.
Other than Douglas, they have no WRs since Bourne went down.
And it isn't all on the QB. The QB gets all the credit and blame, but we saw in 2019 when most people thought Brady was on the decline because he didn't play well and in 2020 when he won a Super Bowl, that the players around the QB make quite a bit of difference.
Mac has seriously regressed, but he wasn't the one who made people run bad routes, drop balls in their hands, whiff on blocks, or cause stupid penalties.
