The Clippers' play on defense has slipped since the All-Star break in mid-February.

And that bothers Clippers Coach Vinny Del Negro to no end.

"I don't think our defensive intensity is where it needs to be right now," Del Negro said.

"You see some of our defensive numbers dropping a little bit," Del Negro said, "and I don't like that."

For the season, the Clippers have given up 94.3 points per game, the fifth-best defense in the NBA.
