DALLAS — His motor stayed running, even when Lakers rookie forward Larry Nance Jr. initially sat on the bench. His aggressiveness stayed high, even when Nance Jr. broke his nose after Julius Randle accidentally elbowed him in practice. His sense of humor stayed intact, even when Nance Jr. forgot his hotel room number when the Lakers stayed in New York amid their weeklong trip.Through it all, Nance Jr. has emerged as a promising development amid the otherwise sour start to the Lakers season. They are 1-7 entering Friday’s game against the Dallas Mavericks (4-4) at American Airlines Center. After sitting the first four games, Nance Jr. has averaged 6.8 points on 70.6 percent shooting and 4.3 rebounds in 18.3 minutes in the past four road contests.All of which led Nance Jr. to provide more laughs instead of rookie platitudes. Newsroom GuidelinesNews TipsContact UsReport an Error “If there was one place I would’ve liked to play my first couple of games, it would’ve been at Staples Center,” Nance Jr. said. “I made sure I gave [Byron Scott] a piece of my mind about that.”Nance Jr. was joking, of course. Beyond his expected energy and leaping ability, Nance Jr. has also emerged with a dependable jumper. Nance Jr. made all six of his shot attempts in Wednesday’s loss in Orlando, including his first career 3-pointer. “I love the energy he plays with and I love the calmness he plays with,” Scott said. “He’s starting to feel confident that he can shoot it.”Nance Jr. attributed his quick growth to making between 250 to 300 jump shots a day and starring for all four years at University of Wyoming.“I’m not taking anything away from the young guys to the guys that come out early. Obviously you can look around the league and you can look around our locker room,” said Nance Jr., whom the Lakers selected 27th overall. “But I think we’ve grown up mentally and may be a little bit more ready physically.” Still, Nance Jr. has learned some things.In a recent game, Lakers forward Metta World Peace told him to run back on defense instead of trying to find a lost contact. World Peace said something similar after Nance Jr. absorbed more contact on his broken nose.“I was out of it,” Nance Jr. said. But World Peace told him, “We have a game to play. Snap out of it.”Nance Jr. apparently forgot in last week’s win in Brooklyn about taking credit for Roy Hibbert’s foul.“He said, ‘You have to raise your hand and say it’s on you,’” Nance Jr. recalled Hibbert said. “I can’t have that foul.”Nance Jr. also does not sound too enthused about Lakers’ strength and conditioning coach Tim DiFrancseo insistence on grass-fed foods.“He’s got some peanut butter bars I like,” said Nance Jr., who’s used to eating Ramen Noodles and Burger King. “But I’m not eating salad.”Nance. Jr’s appetite for defense, though, is a different story.“I try to key in on getting every defensive rebound,” Nance Jr. said. “My main goal is the man I’m guarding doesn’t score. For the most part, I’m very happy with that.” Injury updateThe Lakers listed Kobe Bryant as questionable to play in Friday’s game in Dallas because of lingering back soreness. Bryant has missed the past two games.
