Allen’s leading Brooklyn ... just not to wins

LAS VEGAS — There have not been many bright spots in the Nets’ winless summer-league schedule. Jarrett Allen has been one of the few, both his play and his leadership.

Brooklyn lost 109-102 to undefeated Houston in the summerleague playoffs Wednesday. But Allen — who sat out the first two games in Las Vegas — had a second straight strong performance. Even more important than his defense or his double-double was his demeanor, as he continues to come out of his shell.

“If you strip down summer league and have minimal goals, that’d be a premium for him,” said Nets assistant Jacque Vaughn, who is coaching the summer-league team.

“Whether it’s to communicate with a referee where he thought he got fouled first, whether it’s telling a teammate to sprint back, it’s getting him in different scenarios and letting him show all his abilities to lead. He has it in him, and this summer league was a little precipice to hopefully more things to come.”

The Nets need some life and a silver lining out of a disappointing stint in Las Vegas — with their next chance coming Friday in an afternoon loser’s-bracket tilt.

Milton Doyle — who had a two-way contract last season and is trying to earn another for this season — bounced back from Monday’s four-point, 1-of-10 shooting nightmare with a gamehigh 21 points and six assists. Israeli pro Shawn Dawson added 15 points, and now is averaging a team-high 12.3 points.

Allen had 13 points and 11 boards while altering numerous shots.

“Coming out here I get to experiment with new things. That’s a big step,” said the 20-year-old Allen, who is experimenting with being a leader on the Nets’ threadbare roster.

Rotation player Caris LeVert won’t play a single second in summer league, rookie draftees Dzanan Musa and Rodions Kurucs haven’t finalized buyouts from their European clubs, stash pick Juan Pablo Vaulet is out with a foot injury, and two-time Chinese league MVP Ding Yanyuhang already departed with a sore knee.

The Nets’ summer-league contingent is exceptionally young and inexperienced — the perfect test for the quiet Allen’s leadership skills, now that he’s playing.

“It’s been good. I’m obviously really out of my comfort zone,” Allen said. “Normally on the regular team we’ve got all these older guys, older vets to have leadership for us. Now I’m here doing it for them.’’
