George Allen said yesterday that, yes, he missed Washington, that he left part of himself there when he took off to coach the Los Angeles Rams the second time around.

Maybe he was feeling expansive after doing 150 situps at one time, a performance he mentioned here as the National Football League assembled all 28 head coaches to meet media representatives.

At one phase of his exchanges with reporters, Allen said, "There will never be another era like this (his tenure) in Washington. They always wanted the Redskins on television. Wherever you went across the country, people talked about the Redskins. They had not hand a winner in Washington in 15 years (he forgot about Vince Lombardi's 7-5-2 season in 1969).

"We got standing ovations from the fans for seven straight years. We had seven straight years of sellouts. There were 10,000 persons on the waiting list for season tickets. We had a 40-10, 1 record at RFK.

Allen spotted a league functionary and suggested. "You ought to get a picture with me of the six head coaches here who were my assistants -- the George Allen Alumni picture (Ted Marchibroda, Baltimore; Mary Levy, Knasas City; Pete McCulley SanFrancisco; Dick Vermeil, Philadelphia; Jack Patera, Seattle, and Jack Pardee, Washington).

He was asked if he would send a copy of the picture to "the fela at 15th and I street NW" the office of Redskin President Edward Bennett Williams.

"Who tends bar there?" Allen said.

Someone asked Allen what kind of a season the Redskins will have under Pardee.

"They should have a fine season. If I were there, I would expect a heck of a season and a shot at the title. It's still the same team. There's no reason why they can't win. Of course, if they don't win, they will blame a guy named George Allen."

Did he think Billy Kilmer or Joe Theismann would be the quarterback?

"It should be the same as I did it . . . No change. There is no reason to. When I went to the Rams the first time there wasssome of that stuff about Bill Munson and Roman Gabriel. I said Roman is our starter. And he was voted the NFL's most valuable player the next year."

Allen was asked if he remains interested in trading for Kilmer.

"I don't think there's any chance," he said once more, then added, I don't think they want to trade with us. I don't know why. Anybody who didn't want kilmer would have to have his head examined. All he did was to win big games. He was always ready. . . dedicated . . . a leader. Of all the trades I made for the Redskins, that had to be the best. I'd say our chances of getting him are very slim."

Rookie Coach McCulley of the 49ers was sitting at the same table as Allen and was asked if he might end up with Kilmer, a popular figure in San Francisco. Mr McCulley pointed to Allen and said, "There's the man who is going to get Kilmer."

Pardee was asked to comment on Allen's suggestion that the Redskins did not seem to what trade with Allen for Kilmer.

"George is right," Pardee said. "We don't want to trade with Billy, because we need Billy ourselves."

Allen was asked if he received mail from Washington fans. "Yes," he said, "And it was all positive. I have nothing but fond memories of Washington. We led the nation in getting summer jobs for youngsters.

"I answered all the mail. Even before I felt, a guy who has lived in D.C. all his life, who went back to when there was a Senators baseball team and no basketball or hockey team, wrote, 'We haven't had many winners. I was sorry to see you go. Things will never be the same.'

"Mayor Washington said, after the previous riots in Washington, that in the 1971-72 seasons the Redskins brought the city together. These are things that don't happen to you in a lifetime. It (the Allen era) was like a new frontier for the area . . .

"Earnest Cuneo wrote me a letter on the eve of our last game against the Rams, talking about our character in the face of adversity. I read it to the players before the game and about 40 guys asked for copies, it was so good."

Allen said in reply to a question that the Ram job this time is different because he doesn't have to rebuild as he did the first time in Los Angeles and in Washington.

"The Rams have won the last five years. We will have to find out how to win a little more. I'd rather rebuild; you can motivate a last-place team easier."

Was he implying that the Rams will be hard to motivate?

"No, it will just be harder. The Rams haven't done as well as they had hoped. We will try to find the missing ingredient. Carroll Rosenbloom has a good mind,in football and business. He has given us everything we have asked for and more. He's an active owner . . . he wants to win so badly, and that's a good thing.

"Chuck Knox and his staff did a tremendous job before us; I don't want anything to reflect on them."

Asked if he had declared who is his No. 1 quarterback, Allen said, "Yes, Pat Haden. I visited him for six hours in Oxford, England. I asked when would be best dates for him for a minicamp. He told me and I arranged it last weekend. He flew in from England for it and flew back the day it was over, 5:30 p.m. Sunday."

As if to disprove that he only thinks of defense, Allen said, "I pledged a multiple offense when I went to Los Angeles . . . Not as involved as Dallas.' We will shift and double shift. We will put a man in motion. We will give defenses two or three looks.

"I planned to do it in Washington if I had stayed. Joe Walton (Redskin offensive coordinator) will tell you that."
