Kevin Porter stutter-stepped and twirled with apparent ease, showing no visible effects of the torn Achilles' tendon that sidelined him all last year.

Kevin Grevey sat in the stands, watching, unable to participate because of the same torn abdominal muscle that slowed him late last season.

The tale of two Kevins is one of the major story lines for the Washington Bullets, who opened training camp yesterday at Fort Meade. How well the two veteran guards progress will help determine what kind of team the Bullets have this season.

If Porter can come back, he could help in a number of areas. If Grevey can't, there will be a scramble among at least four players for his spot in the lineup.

Coach Gene Shue said he will wait to see how effective Porter is. He also said he is not planning on Grevey's being available for some time. There already has been talk that Grevey may start the season on the injured list.

"I have to approach this as if we won't have Kevin (Grevey) for a while," Shue said. "That makes that guard spot wide open."

Waiting to fill it are Billy Ray Bates and Keith Herron, acquired this week off the free agent lists, Don Collins and Nate Davis.

"I don't have any idea how long I'll be out," said Grevey. "We could be talking about a couple of weeks or longer. I just don't know.

"It is a lot better than it was, though. This summer I couldn't even pick up a tennis racket, let alone play tennis or even golf. I know I'm going to be way behind when I do come back, but I already know the system and they (the Bullets) know what I can do."

Porter, knows his career is at stake.

"I know I'm nearing the end," said Porter, 32, between yesterday's two workouts. "It's just a matter of overcoming a lot of mental things. I'm just going to do what I can. I'm going to go hard and not hold anything back. I can't afford to."

Porter said he was about 80 percent effective. "I haven't been on the court that much," he said. "I've been running a lot, but not playing much basketball. I've been trying to get my wind back.

"I just want to make the team and play. I'll think about starting and that stuff later. Right now, though, I love the game and I'm never going to give up. If I'm put on waivers, cut or traded, it won't be because I didn't try my hardest. I'm a battler."

Nineteen players worked out in the morning and all 20 in the afternoon. Forward Steve Lingenfelter missed the morning workout to take a stress test.

"It's going to be hard trimming this team," said Shue. "We've got a lot of people and we want to get a good look at all of them, especially the people we signed late. In about a week we'll have a better idea of what they can do."

The Gene Shue Invitational Mile was won by free agent Anssi Rauramo of Finland in 5 minutes 20 seconds. He also earned the nickname "Lasse," after Lasse Viren, the Finnish distance running star. Frank Johnson was second in 5:25, followed by Bates, 5:30. Center Rick Mahorn was last in 7:30. "Wes (Unseld) must have helped Rick with his running all summer," said General Manager Bob Ferry . . . The first team yesterday was Greg Ballard and Spencer Haywood at forwards, Frank Johnson and Collins at guards and Rick Mahorn at center. The second team had Bates and John Lucas at guards, Charles Davis and Jeff Ruland at forwards and Jim Chones at center.
