John Wall and JaVale McGee both joined the solid Wizards contingent at the Impact Basketball Competitive Training Series in Las Vegas on Wednesday, and the duo provided a solid inside-outside combination. But the G team — which also included Jordan Crawford, Rashard Lewis, Shelvin Mack and Larry Owens — lost, 122-115, to a team that featured Marreese Speights, Kyle Lowry, Corey Maggette and Jared Dudley.

Wall clearly put on a show, as he tallied 42 points, nine assists and eight rebounds. He has been showing off his speed, athleticism and hops all summer, so it wasn’t too surprising to see him throwing the ball off the backboard to himself for a dunk or using a sick crossover to send Coby Karl sliding off-balance. But he also appeared to pack an improved jump shot. According to tweets from the game, Wall made a three-pointer early and shouted, “Y’all better guard me.”

His jumper caught the attention of his opponent, Dudley, who wrote on his Twitter account after the game, “Great intense game vs @jimmywa11 and company!! We pulled out the Win in the end but John Wall jumper is looking nice!! Could get ugly nxt yr.”

McGee finished with 19 points and 10 rebounds, using some decent post moves and a jump hook to get buckets inside, but he lost his head-to-head battle with Speights, the Philadelphia 76ers center who had 30 points and 10 rebounds and also dunked on him twice.

Wall was expected to play in only one game in Las Vegas this week and return to play all of next week after spending some time in Washington on Saturday to appear at a charity basketball game at Coolidge High and host another birthday party with R&B singer Chris Brown at Love. Another Wizard could also be in Las Vegas next week, with A. Sherrod Blakely of reporting that Josh Howard has committed to play in the “lockout league.”
