Spanish-speaking forward Ruben Wolkowyski doesn't speak English, and that could hinder his chances of making the Mavericks' final roster.

"Ruben has a lot of individual skills," Mavericks coach Don Nelson said. "He can shoot, he can drive, he can pass, he can run. But it's just his understanding of what's needed out of him.

"There's a language barrier there ... the understanding of where he needs to be in a lot of different situations holds him back. It's communication on the court. He's reluctant to say things because of his English."
