TORONTO — The sacrifice by Terry Rozier is appreciated, one that Jimmy Butler acknowledges he would have had trouble with at midcareer and in midseason. “I’m not going to lie to you,” Butler said, “I don’t think I could do it. But kudos to him for doing whatever the team needs for him to do.” For a week now, after five weeks this season and four years before that of starting, Rozier has played off the Heat bench as part of Erik Spoelstra’s rotation reconfiguration. As the Heat headed into Sunday night’s game against the Toronto Raptors at Scotiabank Arena, the result largely had been positive. “Whatever role this is, he’s really important,” Spoelstra said.
