If Brady were to sign elsewhere, Rapoport said one of their backup plans might be Dalton.
"It doesn't sound like there's been any hardcore negotiations between teams and the Bengals, but they're certainly looking at it," Rapoport said.
Cincinnati, of course, holds the No. 1 overall pick in the 2020 draft and is expected to take a quarterback.
Dalton started 13 games in 2019 but was benched in Week 9 before reclaiming his job a month later. The 32-year-old is under contract for $17.5 million dollars next season, so a restructure could be in order once he lands on a new team.
"It might not be something that's on the front burner," Rapoport said, "but it does sound like Dalton eventually will be traded this offseason."
