Jim Haslett, here setting up a training camp drill in 2010, on Sunday will face off with Packers head coach Mike McCarthy, who worked under Haslett in New Orleans from 2000-04.

When Redskins defensive coordinator Jim Haslett coaches his unit against the offense of the Packers offense, he will match wits with Green Bay head coach and play caller Mike McCarthy.

Haslett and McCarthy are rather familiar with each other. McCarthy served as Haslett’s offensive coordinator in New Orleans from 2000 to 2004.

The two met as opponents in both 2006 and 2007 when McCarthy was head coach of the Packers and Haslett served as defensive coordinator of the St. Louis Rams. The Packers and Rams split those meetings. Then, in 2010, Haslett and McCarthy met again, and the Redskins won, 16-13, in overtime.

Asked this week, who has better familiarity with the other, McCarthy gave the edge to Haslett.

“I really hadn’t given it much thought until you asked me, but I think Jim is probably more familiar with me,” he said via conference call. “I had the opportunity to work for him. I was very blessed for that opportunity, and we’ve had a chance to compete against one another. Jim is very, very, very respected in our building, both by our coaches and our players, so this is going to be a big challenge for us.”

Haslett acknowledged having good familiarity with McCarthy’s philosophies, but said that doesn’t mean he can predict McCarthy’s every move.

“I used to sit in his meetings all the time,” Haslett said Thursday. “As the head coach, I would sit in the offense’s meetings on third down and the red zone, so I know how he thinks. I don’t know what the hell he’s going to do, but I know how he thinks.”
