WALTHAM —  Communicating would seem to come very naturally for Nate Robinson. But what the three-time NBA dunk champ learned Wednesday on the first full day of Celtics practice for him and Marcus Landry was a bit of a surprise.

The Celtics coaches told him they want him to “talk” and “be loud” – specifically when he’s on the court.

“Talking on defense,” Robinson said. “They want you to be loud and talking. I’m a loud person but sometimes in basketball some of the guys that talk a lot are not the ones who talk on defense. But they bring out the best in me and I’m looking forward to this.”
