Rozier acknowledged that he had to weigh the balance of contributing to a contender or seeking a more high-profile and less predictable role. His frustration never boiled over into a trade request. “If you know me, I’m not one to stir the pot,” said Rozier. “That’s not me. That’s not how I do things.” He proved his value in last year’s playoffs, and he can continue to do so in a reserve role on another deep run. Come July, Rozier can revisit the choice between re-signing with a star-studded roster in Boston or seeking a more lucrative opportunity elsewhere. That decision may already be made, or the Celtics might make it for him, but he’s not going to let it get in the way of his success. Not anymore. “I just need to play my game,” said Rozier, “and the rest of that stuff will work itself out.”
