Don’t expect much bold talk from the Dallas Mavericks as they enter the second round for the first time in 11 years and face the 64-win (and suddenly full-strength) Phoenix Suns. They are well aware how good the Suns are. Behind the scenes, though, team officials are expressing clear confidence that they will re-sign Jalen Brunson in the offseason. Detroit and Indiana are two teams with considerable cap space known to have interest in signing Brunson this summer. New York’s interest has also been well-chronicled, even though the Knicks will have to make some moves to create sufficient financial flexibility to compete with the offers Brunson is expected to command that could exceed $80 million over four seasons.
