- The Celtics made a controversial move by trading for Kristaps Porzingis during the offseason. Jayson Tatum says the team is reaping the benefits of having his large presence in the lineup, Jared Weiss of The Athletic tweets. “We haven’t had a low post presence like that since I’ve been on the Celtics and it creates so many problems. Are you gonna switch us? Are you in drop?…I’m just happy to be on this side of it,” Tatum said.
