Ultimately it was best for the franchise.
The run was over and it was time to pay the bills. If Brady stayed there is no way they win in 2020. There were no resources to work with to improve the team that struggled in the second half of 2019, with brady putting up awful numbers. Sure Brady probably could have willed them to 9 wins maybe even 10 and a one and done. That would have taken about 50 mill away from money available for the rebuild.
Rebuild a mediocre team with a 44 year old QB and little money to spend or with a new QB and 60 mill to spend?
As of 1/4/20 when Brady threw the pick 6 to end the 2019 season anyone looking honestly at the team, the cap situation, the play of Brady over the previous 2 months, and his birth certificate would have admitted this team was not going to win a SB before Brady was too old to lead them there.
It sucks, but it is what it is.
Today people are griping about the free agents brought in, had we kept Brady they would be griping about why they didn’t bring anyone in to surround him, and why he is getting killed behind a bargain basement OL, far worse than the one we have.
