Ja Morant likely understands how former Memphis Grizzlies teammate Dillon Brooks felt.Brooks, now with the Houston Rockets, earned the nickname “Dillon the Villain” for his physical play, mean mugging and accumulation of technical fouls. While Morant, the Grizzlies star guard, hasn’t reached that level, he is earning a reputation for his behavior.Morant and the Grizzlies (45-32) visit the Detroit Pistons (43-34) on Saturday night, trying to stage a strong late-season run to remain out of the play-in tournament.The Pistons secured an Eastern Conference playoff spot Friday with a 117-105 win at Toronto.Morant was fined $75,000 on Friday by the NBA for his on-court gun gesture during Thursday’s road win at Miami. The NBA warned him following a similar incident during a home loss to the Golden State Warriors on Tuesday.His “finger gun” caused the Heat fans to loudly boo him. Morant didn’t seem to mind.”I’m kind of used to it,” Morant said. “I was pretty much a villain for two years now. Every little thing, If somebody can say something negative about me, it’s going to be out there. Yeah, I don’t care anymore.”Teammate Jaren Jackson Jr. said Morant feeds off such crowd reactions on the road.”I wouldn’t boo him,” Jackson added.Morant’s gun gesture and game-winning shot at the buzzer aside, Friday also served as interim coach Tuomas Iisalo’s first win. Iisalo moved into the role after the Grizzlies dismissed Taylor Jenkins on March 28. Iisalo’s first three games as coach were against the Los Angeles Lakers, the Boston Celtics and the Warriors.”(The win over Miami) was extremely important for our team,” Iisalo said. “Guys have been working really hard. Everybody that has been around has done everything in order to get this first win. Hopefully it’s one of many this season. It feels great.
