GREEN BAY, Wis. -- Josh Sitton would hate the idea of joint training camp practices.

He shouldn't have to worry because Green Bay Packers coach Mike McCarthy and general manager Ted Thompson agree.

On the same day McCarthy and Thompson explained why the Packers haven't conducted joint practices since 2005, when the Buffalo Bills came to camp, the Packers' outspoken left guard explained why he thinks they're "kind of stupid."

"I have a feeling if we had any joint practices that I'd be watching from the sideline," Sitton said. "I'm not a big fan of those. It's kind of stupid. It's just inviting fighting. It happens every single time. It doesn't matter. I'm not a fan. I don't think Mike is, either, so I don't think he would ever do it. I'm definitely not a fan."

While fights seem to be breaking out all over training camps, especially at the joint practices, the Packers have gone three weeks and 13 practices without anything that even closely resembled a fight in training camp.

There was a minor shoving match way back on Aug. 7 between offensive lineman David Bakhtiari and defensive tackle Bruce Gaston that was little more than a shoving match.

Sitton said he believes camp has become more tame because the Packers' group of core veteran players has grown.

"We've kind of learned that fighting makes you tired," the 6-foot-3, 318-pound Sitton said. "You try and avoid it. But when it comes down to it, you defend your guys. Right now, it's offense versus defense. It's training camp. That's how it goes. You defend your guys."
