Saturday morning’s All-Star practice is a show for the fans. The half-court shootout and a game of knockout get the place going crazy year after year. LeBron James hit a half-court shot in a sudden-death round to notch a victory for the East in that competition. Then Jrue Holiday did the Sixers proud in knockout. He was one of three left when they called the game a tie between him, Russell Westbrook and Paul George. There was a time, years ago, when coaches would actually try to implement plays during the morning practice. But common sense has prevailed. The weekend is about putting on a show, a show that need not be rehearsed or scripted. Holiday’s personality is a big reason he was in the final three of knockout. He is L.A. cool with a competitive edge, a skill that was honed in a California backyard, where Jrue would battle his older brother, Justin, one-on-one. “We stopped playing one-on-one because we would fight,” Holiday said. “We wouldn’t keep score or anything, but someone would do a better move on the other person, and then one of us would throw a ball at the other, and it would come down to a move in the post, and you would elbow him in the chest or something. So we stopped playing one-on-one in the seventh or eighth grade.”
