The wingspan got Donovan Williams noticed.

Now it’s the work that’s going to have to keep him in the NBA. And in Brooklyn.

While several other Nets hopefuls from Summer League have already come and gone — Brison Gresham, Taze Moore and Yves Pons went to play abroad, and David Duke Jr. entered the limbo of free agency — Williams, an undrafted free agent, survived the cut in Las Vegas and is expected to be in Brooklyn next week.

“It’s everything,” Williams said of his chance to find a place on the Nets roster. “I’m in the gym all the time, whether they’re there or not, whether anybody’s watching or whether anybody’s not. For them to understand and see that improvement I’ve made … and understand that the work I’m putting in is really paying off, it means everything to me, because they’re the organization I wanted to play for. So if they have confidence in me, that goes far.”
