Goff's market would be very different from Brady's. Not sure Brady will just get $30M guaranteed AAV over say, 3 years from any team.
Big Ben is 38 years old and just got a 2yr/68 million dollar deal with 50mil guaranteed. Rodgers is 37 and he's on a 4yr/137mil deal with 98.2mil guaranteed. Denver just gave Joe Flacco 3yrs/66mil with 62mil guaranteed. Jacoby Brissett made 28mil this year, so did Kirk Cousins. 35yr old Matt Ryan just finished year 1 of a 5/150mil deal with 94.5mil guaranteed. Matthew Stafford is at 27mil per year with 92mil guaranteed. The QB market is insane, for everybody.
Like I said before in this or another thread, this is all going to come down to terms, not dollars. If the Pats offer Brady 2yrs/50mil, fully guaranteed, or give him 3/75 with 50 guaranteed and spread out the hit, I think he signs here. If BB thinks he can truly low ball him and offer 15mil, Brady is going to walk, and some team out there is going to offer him 3/90 without batting an eye, just to put asses in their seats. If BB tries to continue going year to year with TB12, he's going to walk. I think that's why he didn't want the possibility of a franchise tag. He wants a commitment from the team, in terms of years, and he's going to want them to put players around him.
There is no solution involving a free agent QB that will result in this team winning more than 7 games, IMO. If you lose Brady and have to eat his 13.5mil in dead money this year, you need to just blow it up, roll with Stidham and get as high into the draft as possible.
