It's June, so you know what that means it's time to do if you're Udonis Haslem: absolutely never retire from the NBA. Never, not once. Every season since 2003, Udonis Haslem has ended the year as a member of the Miami Heat. From entering the league in Dwyane Wade's rookie season to now playing with teammate Precious Achiuwa, who was four years old when UD got started, Haslem has experienced every kind of season in a Heat uniform and decided to return the next season for another go at it. Unbelievably, he'll have to make that same choice in 2021. There really should be no choice, though. Haslem should return next season for his would-be 19th in the league. UD, if you're reading this, we hope our reasoning can sway you.
