TB12 Facility and Garoppolo
Tom Brady has had a handful of backup quarterbacks throughout his career, Garoppolo potentially being the most talented of them all. According to ESPN, Brady viewed him as a threat and wouldn’t mentor him or provide much help.
"“And Brady is famously unhelpful toward his backups — or, at least, a threat like Garoppolo. The two quarterbacks were friendly, but Brady — like Joe Montana to Steve Young and Brett Favre to Aaron Rodgers — didn’t see it as his role to advise Garoppolo, even on matters as trivial as footwork, as nobody had helped him during his climb.”"
And perhaps Brady felt so threatened, he wouldn’t let Garoppolo train and rehab with his TB12 trainers, especially after Garoppolo’s shoulder injury.
"“But after Garoppolo was knocked out of his second start because of a shoulder injury, he set up a visit at TB12. As he later told Patriots staffers, when he arrived, the door was locked. He knocked; nobody was there. He called TB12 trainers but nobody answered. He couldn’t believe it, Garoppolo told the staffers, and that night ended up visiting team trainers instead. Guerrero vehemently denies ever refusing to see any player, and Garoppolo was eventually treated at TB12 — but it was two weeks after he showed up for his original appointment, and only after a high-ranking Patriots staffer called TB12 to inquire why Garoppolo hadn’t been admitted.”"
But since the article’s release, this story has its flaws. Patriots beat writer, Mark Daniels of the Providence Journal, explained how “Garoppolo visited the TB 12 Center to receive treatment before and after his shoulder injury. He even had his own passkey to enter the facility.”
Brady never told Guerrero not to train and help Garoppolo, and the two did work together when the injury occurred.
