It will damn near kill me to see Brady suit up for another team.
I don't think Brady would find a better suitor than the Patriots if he were to seriously explore FA for the following reasons:
a.) He is going to be based in CT. The nearest teams will be NJY, NYG, and the Pats. The former 2 just spent a first round pick on a QB.
b.) What other team would pay him 30M a year? Even on an one year deal? Oakland...to sell tickets...maybe...the Chargers to sell PSL's for the new stadium...maybe....maybe even the Bears to name a few...but any other team pretty much doesn't have an attendance problem or already has an established QB or already is in rebuilding mode.
c.) Despite the lack of game breakers in Foxboro....in 2020...the Patriots D will lose some players(DMac, KVN, and Collins I believe), but probably still be ranked in the top 10....N'Keal Harry and Meyers will take a step forward....Edelman will be half a step slower...Snau will have more experience in the system...and we are very likely to upgrade at TE (no way to go, but up and FA's avail like Henry, Hooper, Ebron, Doyle, Eifert)...and get Develin back. I think the only MAJOR FA we have on the offensive side other than Brady is Thuney. There are FA WR's like AJ Green (if healthy), Fitz (long in the tooth, but can make plays), Amari Cooper (doubtful tho), and etc.... if we get some healthy bodies all year from August to January.....we should be much better on offense.
==================
IMO, it's retirement or play for the Pats in 2020. Personally, if I were BB...I'd just write a check with a HUGE signing bonus and back load salaries on the end. Something like 3 years 100M with a 51M signing bonus and salaries of 10, 15, and 24M....for cap numbers of 27M, 32M, and 41M. Then we can renegotiate the salaries every year if needed....and cut Brady before year 3 for a 17M dead money hit.
Right now, I don't care if Brady blows up our cap...I want to watch him play all the way to the bitter end.......
