Brady made the comments when he met with reporters Monday on a Zoom video conference. The six-time Super Bowl champion will play in his 10th Super Bowl on Sunday in Tampa, Fla.
Brady joined the Tampa Bay Buccaneers last off-season after he spent 20 years with the Patriots. The move has led critics to question if Brady or Belichick played a more significant role in helping the Patriots win six championships.
"I have a great relationship with [Belichick]," Brady said. "I'm incredibly grateful for what he has meant in my life as a coach. He was everything you could ask for as a player. I loved my time there. I had two incredible decades there."
Brady completed 65.7% of his throws for 4,633 yards, 40 touchdowns and 12 interceptions this season for the 11-5 Buccaneers. Belichick's Patriots -- sans Brady -- failed to make the playoffs for just the second time since 2002. The 2020 Patriots (7-9) also had a losing record for the first time since 2000, the year before Brady took over as the full-time starter.
"I could have never accomplished the things I did without his support, his teachings," Brady said of Belichick. "He is an incredible coach and mentor for me. I've had a lot of those in my career, but he is at the top of the list."
Brady did not respond when asked if he has heard from Belichick this week.
The future Hall of Fame selection signed a two-year, $50 million contract when he joined the Buccaneers in March. Brady, 43, has said he plans to play into his mid-40s, but said Monday that he could play beyond 45 years old.
"I would definitely consider that," Brady said. "It's a physical sport. You never know when that moment is, because it's a contact sport. I have to have 100% commitment to keep doing this. I've been very fortunate over the years."
Tampa Bay hosts the Kansas City Chiefs at 6:30 p.m. EST on Sunday at Raymond James Stadium. The Chiefs are 3.5-point favorites to beat the Buccaneers.
