“I wasn’t raised to be no punk.”Those memorable seven words from Dennis Smith Jr. summed up perfectly his first All-Star weekend experience.He acted wise beyond his 20 years. And his poise indicated that he belongs on this sort of stage.Heck, he didn’t even raise (much of) a stink when he got jobbed on the dunk contest scoring.Just like he doesn’t get too animated when referees don’t call fouls on his aggressive drives to the basket.And just like, as he said, he didn’t hang out at any of the wild parties for which All-Star weekend is legendary.Yes, the Mavericks’ rookie is pretty good at this game.
