First your narrative that the Pats kicked Brady out is a lie. Brady LEFT for greener pastures. He knew the Pats were going to go through ANOTHER rebuilding process and he rightfully realized that he needed to go to a team with a better roster if he was going to win #7 They DID invest in him HEAVILY from 2014-19 and put themselves in cap hell doing it.
There is one thing I always ask someone who thinks the Pats should have resigned Brady for $25MM/yr in 2020. Remember that year, with a stripped down roster already, and a QB that cost them $1MM against the cap, and they were STILL in cap hell in 2020 (not to mention that it WOULD have been even worse if Covid hadn't happened and HIghtower, Chung, etc had to count against the cap). Who ELSE would have had to go in order to give Tom his money.
No it made NO sense at all for Tom and it made no sense for the Pats. The PR could have gone better, I guess, but as a football decision, the CORRECT move was made by BOTH parties.
