The NCAA Men's Basketball Rules Committee, which will meet here Tuesday, is expected to implement a three-point shot in some conferences on an experimental basis next season, Ed Steitz, the NCAA rules editor, said tonight.

Steitz said he would like the Big East to be one of the conferences. He did not indicate at what distance the line would be located. The three-point shot was used in three conferences this season: Atlantic 10, Pacific Coast Athletic Association and Western Athletic.

Steitz said more research is necessary before the rule is passed. Such was the case with the 45-second clock, which was used on an experimental basis by 25 conferences this year.

A number of coaches want the three-point shot to be instituted in concert with a 45-second clock, which Steitz said the committee "definitely" would pass at this meeting. Those coaches, led by North Carolina's Dean Smith, say a three-point shot is necessary with a shot clock to prevent teams from packing in zones.

The 13-member rules committee also is expected to consider widening the foul lane to lessen congestion around the basket and to discuss ways of eliminating fouling-for-profit by trailing teams in the last minutes of games.

Now that Gene Bartow and Lute Olson have turned down the University of Kentucky basketball coaching job -- and a reported half-million dollar annual salary package -- sources close to the program say it is unlikely either Lee Rose or Dick Parsons will get the job.

Rose, who took Purdue and North Carolina-Charlotte to the Final Four before becoming coach at South Florida, and Parsons, a former Kentucky assistant, each has strong ties in Lexington and has lobbied for the job. But sources here say Kentucky President Otis Singletary wants to bring in someone who has no obligations to fulfill.

Olson's decision to remain at Arizona didn't surprise many coaches here for the National Association of Basketball Coaches convention. They consider Olson a private person who went to Arizona because the Iowa job had put him in a fishbowl, "a mini-Kentucky situation," as one coach put it.

Approximately 3,000 Georgetown students watched the game last night on a large screen (15 feet by 20 feet) television hookup at McDonough Arena.

Classes were canceled yesterday because of the game, but no further cancellations were scheduled.

A welcome-back rally for the team will be held Tuesday at approximately 4:30 p.m. at Healy Circle at 37th and O streets NW. The rally is organized by the Georgetown University Student Association.

Dave Maggard, the athletic director at California-Berkeley, is making the effort to get a big-time basketball coach. Among the coaches to whom he has talked recently are Navy's Paul Evans, Virginia Commonwealth's J.D. Barnett and New Mexico's Gary Colson.

However, the job, with fringe benefits, is worth only about $110,000.

Alexander Severance, former basketball coach at Villanova, died this morning at his Lexington hotel room, apparently of a heart attack, hours before he was to watch his former team play in the NCAA championship. He was 77.

Severance coached Villanova from 1936 to 1961, leading the Wildcats to their first tournament appearance in 1939.
