While Tom Brady and Bill Belichick had a lot of success together with the New England Patriots, there was some tension there by the end of the their run, which helped drive Brady to the Tampa Bay Buccaneers. Alex Guerrero, Brady's longtime personal trainer and TB12 partner, recently shed some light on this.

In an interview with the Boston Herald, Guerrero dropped a major revelation about the Brady-Belichick relationship with the Patriots:

“The interesting thing I think there — and this is just me, an outsider looking in — it was like Bill never really . . . I think his emotions or feelings never evolved with age,” Guerrero said. “I think in time, with Tom, as Tom got into his late 30s or early 40s, I think Bill was still trying to treat him like that 20-year-old kid that he drafted. And all the players, I think, realized Tom was different. He’s older, so he should be treated differently. And all the players, none of them would have cared that he was treated differently. I think that was such a Bill thing. He never evolved. So you can’t treat someone who’s in his 40s like they’re 20. It doesn’t work.”

Guerrero now thinks Brady is in the perfect situation with the Buccaneers after the 20-year run with the Patriots. It's hard to argue against that given Brady just won his seventh Super Bowl last season and is looking like an early MVP candidate at the age of 44 in 2021.

Still, it's interesting to see these accusations against Belichick. Guerrero and Belichick didn't exactly see eye to eye, with the Patriots coach barring the trainer from the team facility. So, there's probably a bit of a grudge here, especially considering the Buccaneers are so welcoming of Guerrero and that other players work out with him at a TB12 center near the stadium in Tampa.

If forced to answer honestly, Belichick would probably take some issue with these statements. But in the end, it's not all that surprising that two highly successful people like Brady and Belichick would wind up beefing after so much time together, even with all the Super Bowls.
