Leonard Hauss has heard or read all the talk about the need to improve the Redskins' offensive line, about the so-called open competition for every position on the team and the implication that the Redskins will be a young man's team under Jack Pardee.

But after 14 years in the professional game under a half-dozen head coaches, you will pardon Hauss for not getting worked up about the new look or the new way in this, the latest, era of Redskin football. It's not his style.

"What's so different?" he asked yesterday after a morning practice. "It's 11:42, I just came off the field and I've been doing that at the exact same time for 15 years. I'm hot and I'm tired, so tell me where the difference is.

"I feel like I'm doing the same job I always did. I feel as fast, as strong and as quick as I ever did. So I don't feel any pressure. Why should I feel it?" It looks to me like the pressure is elsewhere.

"Any time you replace a player, me or anyne else, there are two ways you can do it. You either give the man the job, or give it to the guy who does it better than the other person. It holds true in your line of work, or anywhere else."

For years, Hauss has played the center position better - and longer - than most of his past or present colleagues around the NFL.

He will go into the 1978 season with a remarkable streak of having played 196 straight games, 192 of them as the starting Redskin center. Only seven other men in the history of the game have played more consecutive games.

For Hauss to keep that gaudy record going, he must beat out Bob Kuziel, his backup the last three seasons and a young man eager to earn a starting job.

The coaches are saying Kuziel is having a terrific training camp, but they do not go much beyond that. Ray Callahan, the offensive line coach, also will tell you Hauss is "really working hard, hustling, and you can tell every day how much experience he's get." But he also will insist it is far too early to make any final decision.

The staff also keeps talking about the need to improve the play of the offensive line, a unit that allowed 52 sacks of the quarterback in 1977 and shared part of the responsibility for the dismal Redskins' offensive showing.

They have moved Terry Hermeling from guard to tackler, demoted Tina Stokes to the second team, promoted Dan Nugent to right guard and brought in a flock of young players.

"So what's different about that," Hauss asked again. "I heard they want to improve the line every year. No, it doesn't disturb me. Why should it? I know how I played. And I know what I have to do. That doesn't change, either."

He also insisted the change from George Allen to Jack Pardee, the change in line coaches from tough-talking Bill Austin to Callahan, a gee-whiz, pat-on-the-rump type, has had very little affect on his life.

"Do I miss George? I miss him the same way I miss (Vince) Lombardi, the same way I missed (Bill) McPeak when Otto (Graham) came in. Every coach I played for has been a good coach. I respected all of them. But I don't think I played any different for Graham because I missed McPeak.

"Any player who worries about who he's playing for has a problem. I play for the Redskins, and that's how I've always looked at it."

Hauss also is president of the NFL Player's Association and played a major role two years ago in settling the long and bitter contract dispute between the union and management that resulted in a landmark collective bargaining agreement.

He has only three semesters remaining to earn a law degree from John Marshall in Atlanta. So why does he keep playing football and how long will he stay in the game?

"Basically, I still enjoy it," he said. "When I get out there and I find I can't keep enjoying what I'm doing, then it'll be obvious. But I haven't found that to be the case yet."

Chris Hanburger agreed to terms on a new contract yesterday, a one-year pact with an option clause calling for a salary estimated in the range of $125,000 a year . . . Chuck Rodgers, a rookie cornerback from North Dakota State, will be put out of action four to six weeks after breaking his collarbone in yesterday's afternoon practice. Rodgers made a diving interception near the sideline in one-on-one pass drills but landed hard on his shoulder and had to be helped off the field . . . Tight end Jean Fugett continues to make a swift recovery from offseason knee surgery. Yesterday he went flying down the left sideline in 11-on-11 drills and made a fine catch of a Joe Theismann pass in full stride. The Redskins' rookie scrimmage at 2 p.m. tomorrow against the Colts at Hershey, Pa., will include 7-on-7 passing drills, 7-on-9 running drills and some kicking work, involving all the players on both teams. Rookies and younger veterans also will participate in a 48 play live scrimmage, with each side running two shifts of 12 straight plays against the opposing defense . . . Offensive tackle Jeff William remained in California yesterday and said he was still trying to take car of some personal business before reporting to Carlisle. He was obtained Tuesday in the Eddie Brown trade with the Rams. If Williams decides not to report, the Redskins would receive a draft choice. "We want the player, not the choice," Coach Jack Pardee said. "We want him here as soon as possible."
