Brady is a different animal than the Rodgers situation. True, he's been compensated well over the years. They've been creating cap space by being creative some years. At some point when Brady is done they'll feel that pain. As will we I'm sure though Rodgers hopefully has a handful of years more than Brady left and as it gets closer I'm sure we'll get more creative if it appears Rodgers is still an elite QB at that time.
BUT, I have no doubts Gisselle has eased the burden of Brady's contracts. Let's be real, he's not playing for a million bucks because his wife is a billionaire practically. But I would not be at all surprised if it often meant the difference between 15 million compensation 1 year or 20. or a 25million dollar year vs a 30 million dollar year. I would not be surprised at all if his wife's earnings played a role in total money saved by NE by more than a few million dollars.
