When Nate McMillan assessed Vladimir Radmanovic during training camp, the most glowing thing the Sonics coach could muster was that his English was better than expected.

Now, McMillan's compliments have expanded from the Yugoslavian's linguistic skills to his contributions on the court.

"I think he has earned a spot in the rotation," McMillan said. "He's done a good job defending. He's rebounded, blocked some shots and provided some scoring."

And not one mention about his fluency in English.

The Sonics have lost five of their past seven games, including several blowout losses. And just about the only redeeming thing about Seattle's roughest stretch of the season has been Radmanovic's play.

Before suffering a sprained right ankle that makes him doubtful for tonight's game against Orlando, Radmanovic showed signs of breaking out of his rookie doldrums. Radmanovic received increased minutes after Desmond Mason suffered a bruised right knee on Dec. 2. And Radmanovic ? the No. 12 pick in this year's draft ? stopped looking like a rookie whose only extensive time would come in practices. With a versatile game and surprising toughness, Radmanovic has forced McMillan to reassess his role this season ? even with Mason back.

"He's still a rookie," McMillan said. "You still give him opportunities but you don't put too much (pressure on him)."
