Per Karen Guregian of the Boston Herald, Brady and Belichick had a phone conversation Tuesday that "didn't go well."
A source told Guregian this was the first time Brady and Belichick have talked about the star quarterback's contract. The discussions involved New England's plans going forward, but no additional details about the conversation were provided.
According to NBC Sports Boston's Tom Curran, the conversation "wasn't particularly productive," and Belichick was talking as if Brady was "still under contract."
ESPN's Adam Schefter later added the discussion was "business as usual" for both Brady and Belichick. He also reported the conversation between the two did not take place on Tuesday.
Curran reported Sunday that the dynamic between Brady and the Patriots "is not a Cold War" and that the team hopes to re-sign the 20-year veteran.
Brady is set to become a free agent for the first time in his career when the new league year begins March 18. The 42-year-old is reportedly attracting attention from a number of potential playoff contenders.
ESPN's Jeff Darlington said on The Adam Schefter Podcast (h/t Sports Illustrated's Jason B. Hirschhorn) last month that the Tennessee Titans were viewed as the favorites to sign Brady. The Las Vegas Raiders and Los Angeles Chargers were also mentioned as potential landing spots.
The Patriots offense struggled last season in the wake of tight end Rob Gronkowski's retirement. They ranked seventh in points per game (26.3) but were 15th in yards per game (354.0). Opposing defenses held them to under 20 points in four of their final eight games, including a 20-13 loss to the Titans in the AFC Wild Card Round.
Brady had a productive year with 4,057 yards, but his 24 touchdown passes were his fewest in a full season since 2006. As well, the 14-time Pro Bowler's 60.8 completion percentage tied for the third-lowest single-season mark of his career.
