San Antonio coach Gregg Popovich warned the Spurs that facing a downtrodden team in its first game with a new coach can be dangerous.

The Bucks made a winner of Larry Krystkowiak in his NBA debut, ending San Antonio's 13-game winning streak with a 101-90 victory on Thursday night.

Krystkowiak said he expected a strong effort from his players the first time out.

"A lot of times, you get a little adrenaline and spark," said Krystkowiak, a Bucks assistant who was promoted and given a multiyear deal hours after the team fired Terry Stotts on Wednesday. "I anticipated our guys playing hard."
