The slogan for yesterday's charity football game between former Washington Redskins and Dallas Cowboys at RFK Stadium was "Nothing's Changed." But something was certainly different.

For one thing, this game -- which benefitted the March of Dimes -- was flag football. The only thing uglier than old football players running around RFK's field would have been old football players in shoulder pads running around, and hitting each other.

So the proper dress code for the players was a jersey, running shorts and baseball cap. Did John Riggins follow the dress code? Of course not.

As if he needed anything to stand out during the 1 1/2-hour pregame autograph session, Riggo strutted onto the field wearing an outfit only he could get away with: sneakers, shorts, knit shirt, cool shades, and a cream-colored blazer. But by the start of the game, he had changed into the game uniform.

Some things, it's true, will never change. There was the "Hail to the Redskins" fight song blaring over the loudspeakers. There were the ageless T-shirts saying, "My two favorite teams are the Redskins and whoever is playing the Cowboys." And the Cowboys -- especially Harvey Martin, Charlie Waters and Roger Staubach -- were booed mercilessly by the 10,614 in attendance when the lineups were introduced.

There also was Ralph Campbell, one of the Hogettes who have heckled Cowboys at RFK since the early '80s. But what's this? Campbell laughing and joking with Staubach and Drew Pearson? What's going on here?

"I have a lot of respect for these Cowboys because they're doing this for the kids" at the March of Dimes, said Campbell, dressed in the customary wig, dress and strap-on pig nose. "But once the {NFL} season starts, it's back to normal for me."

And there was legendary Redskins coach George Allen, sprinting onto the field to lead his charges against the cowpokes once again. Without a doubt, he is still the man in charge.

"I'll do anything he tells me to do," said Diron Talbert, who played 11 years for Allen. "If Coach Allen tells me to jump, I'm going to ask how high."

Allen, the head coach at Long Beach State, is the only participant who is still active in football.

"The guys we had here all had great characters," Allen said, rattling off a long list of his former players. "And they're all successful today. That's the kind of players I'm looking for at Long Beach. Not guys who can bench press 400 pounds, but guys with character."

One person who wasn't there was Allen's longtime rival, Tom Landry. "I'd much rather have Tom here and Roger gone than the other way around," said Allen.

The scrambling, bomb-throwing Staubach dominated the game. Roger the Dodger, unlike most of the rest of the players, looked as if he hadn't lost a step. He had a part in all six Dallas touchdowns, throwing for five and running for one. And although there were no statistics kept, it is safe to say Staubach threw for several hundred yards.

And just to show he's human, he tossed a couple of interceptions. "Just trying to keep it close," he joked.

Before the game, the most often spoken phrase was, "As long as no one gets hurt . . . ." Except for sore muscles, no one did.

"When you get a bunch of 50-year-olds playing a 20-year-old's game, you've got to be careful," said Billy Kilmer, who got some of the loudest cheers of the day.

Either the scoreboard was malfunctioning, or Washington was getting two points for every conversion after a touchdown and Dallas only one. But it didn't help the Redskins.

The final score: Dallas 42, Washington 22.
