Not willing to label Gisele "Yoko Ono" here. It's clear they had discussions every season.Definitely think Gisele pushed this more than ever but he had nothing left to prove.
I suspect higher on the list would be that Tampa Bay's Super Bowl window was always small, but likely far smaller in 2022 without enough money or resources to give him a puncher's chance. I'm happy he's not out there getting wrecked while a medium talented team hovers around .500. (And Tampa now was where the Pats were two years ago, when they couldn't reboot or turn the page and get their next cheap legacy QB if TB was still there).
I recall cringe final seasons from Top 10 QB's (Favre, both Mannings, Marino), or seasons where a QB's saddled with a terrible team around them (often due to their own longevity/cap hit like Roethlisberger or Brees) and am glad Brady didn't go out with a sad-as-fuck whimper.
