Dave Butz will renew acquaintance with New Orleans guard Conrad Dobler Sunday. Dobler over the years has gained the reputation as the dirtiest player in the National Football League. Butz, in his five years with the Redskins, has remained fairly silent on the subject.

"It's just a hell of a thing," said the 6-foot-7, 285-pound Butz, who will line up opposite Dobler as Washington's left defensive tackle. "They were touting him, putting him on the ocer of Sports Illustrated, as the dirtiest football player in the league.

"And that's just a fantastic thing for the younger ball players. They see the way to get famous or the way to get notoriety is to be a cheap-shot late hitter, that type of deal.Some little kid is going to figure, 'I'm going to do that too.'

"That could ruin another little ball carrier's career. It's a hell of a thing to have it so publicized as the dirtiest player in the league. It's the wrong kind of example you want your kids to follow. It's such a high risk getting to the top, anyway."

Dobler now plays for the Sanits, not the St. Louis Cardinals, the team on which he became famous with such All-Pro performers as Dan Dierdorf and Tom Banks.

"Dobler hasn't changed," Redskin Coach Jack Pardee said after yesterday's bried workout at Redskin Park.

Butz says Dobler has a method to his madness. "Jack just got through saying he's just as dirty as ever, probably even more so," Butz said. "You see, Connie's got a deal where he tries to get the opponent upset with him. He tries to get people mad at him, start taking swings at him.

"He does everything he can to irritate the person across the line from him. When he does that, the defensive player is not rushing at all, trying to prevent the ball carrier from gaining years. In other words, he tries to get it on a personal level, just the two of you, rather than you thinking of what your job is.

"He wants to get ballplayerss upset with him so if you sit there and throw him around or beat up on him, because (then) you're not pursuing the quarterback or going after the ball carrier. That's his philosophy. It usually comes from people of lesser ability."

Reports that Dobler bites opponents are false according to Butz.

Then, what does he do?

"Most of the time when he's doing his work in is pileups or when you're standing around piles. He hustles real well -- you have to hand that to him. But he's not above, as the whistle's being blown, if he's still got momentum, givin somebody a good shot."

Butz said he used to take his job home with him, watching films and talking with his wife Candyce about ways to stop opponents like Dobler. Now he has banned football talk around his house at night. He found he had reached a point of negative return from his extra work.

"I've got to wait till my son (2-year-old David Ray II) goes to bed. Usually Candy would stay up and watch some of the film with me and then, when she'd go to bed, I'd stay up later and that really didn't help because I found out this year my son's staying up later and the later I play that film, the harder time I have getting rest.

"And that's what you relly need, because when you come out and practice a lot, you get tired. Your muscles get tired. You weightlift. You've got to have sleep enough to rest up and come back refreshed the next day. Well, I found myself getting more tired as the week progresssed, making it harder to come to practice and execute properly."

Now, Butz leave most of his work at the office.

"We set a time limit on which we'd discuss anything about football," he said. "Candy's real good about not bringing stuff up because she gets excited, she worries, too, about houw the team is or about how I'm feeling.

"I just feel more enthusiastic (on Sundays). God know, they drum enough of it into you here that you shouldn't be taking it home. You sould go home, take it easy and enjoy your family and not sit there with a grumpy attitude about what somebody said or what you're going to do or what's going to happen."

Tackle Terry Hermeling and defensive back Tony Peters were absent from Redskin Park yesterday. Hermeling, also nursing a sore leg, was at the dentist with an abscessed tooth. Peters went home to Norman, Okla., to be with his wife Jewell, who gave birth to Tony Jr. yesterday . . . Pardee said he expected tight end Jean Fugett to resume full workouts today. He has been hampered by a knee injury.
