In Los Angeles, normalcy is back. After a mediocre start, the Lakers have returned to the form that made them NBA champions last season. And after a decent start, the Clippers have once again become the league's pushovers.

Perhaps the unhappiest of the Clippers' lot is rookie swing man Reggie Williams. As the fourth choice overall in the June draft, the Georgetown star was regarded as can't-miss, in large part because of his versatility. But Williams' ability to play both guard and forward has turned out to be more of a curse than a blessing. Shuttled around by Coach Gene Shue, Williams has struggled, hitting less than 40 percent of his shots and averaging 11 points a game.

"I don't know my role yet -- a whole lot of people don't know their roles," Williams, now on the injured list, said recently. "I've been a three {small forward}, a two {big guard} and now I'm working as a one {point guard} some.

"I need to find a position. Sometimes I don't know what's going on. If I come out hot, I get taken out. If I don't come out hot, I get taken out. It's back and forth. I don't know how much I'll play in any game. I've never been this uncertain before."

Shue admits things haven't been made easy for Williams: "He started out as a three but he's not really one because he's overmatched there. He's played two but at this point he's not ready to replace Mike Woodson or Quintin Dailey.

"He also has to learn how to play half court. He's an open-court player but we're not an open-court team. He's starting to play the point and that could well be his position. We're excited about that."

Some other Clippers have been chafing under Shue's set offensive style, but Williams said he doesn't care what the style is as long as "the coaches define my position and what they want me to do. Then I'll be happy to do it."Once a Hoya, Always a Hoya

When Sacramento played the New Jersey Nets at the Meadowlands last Thursday, another former Hoya, Kings guard Michael Jackson, warmed up wearing a Georgetown sweat shirt. "I put it on because {Georgetown} lost last night {to Providence}," he said. "I'm going to start doing that."

Indeed, Sunday, the day after the Hoyas got tripped again by Boston College, Jackson was again out and about in the familiar top . . .

The past two years haven't been easy for Calvin Natt. The Denver Nuggets forward missed virtually all of the 1986-87 season because of a ruptured Achilles' tendon. This fall, after making what some felt was a surprise recovery, he scalded an arm in a kitchen accident and missed time.

Natt returned early in the regular season but has recently lost time after arthroscopic knee surgery. While rehabilitating, he discovered what he thought were lumps in the calf below the knee. He wanted to keep the latest development quiet, but friends persuaded him to tell team doctors. That was a good thing. Natt was diagnosed as having phlebitis, an inflammation of the veins that had started causing blood clots.

Had they not been detected, the clots might have traveled to another part of the body and become potentially life-threatening. Given his run of bad luck, Natt was asked if he's starting to consider retirement. His answer: "They'd have to wrap me all up in tape and then drag me off the court first." Working Against Impasse

NBA players union representatives will meet before the all-star game to consider a strike, a boycott of the game, and other actions aimed at breaking their impasse with owners over a new collective bargaining agreement, the New York Times reported.
