We know Martellus Bennett will not be catching passes from Tom Brady next season. He could be catching them from Derek Carr instead. Bennett and the Oakland Raiders have “heavy mutual interest” in one another as the tight end prepares to enter free agency, a source told the Boston Herald’s Jeff Howe on Thursday. After one season in New England, Bennett confirmed Wednesday night he would not re-sign with the team, thanking Patriots fans for their support on Twitter. He played in every game for the Super Bowl LI champions, catching 55 passes for 701 yards and a team-high seven touchdowns. Earlier Wednesday, the Patriots traded for former Indianapolis Colts tight end Dwayne Allen, who likely will replace Bennett as Rob Gronkowski’s backup.
