It is advertised as a "Town Hall Meeting," the 13th and final clinic at the National Association of Basketball Coaches convention here Monday. The main speaker, unadvertised, will be an FBI official. His topic: gambling.

The FBI touched off the recent academic cheating scandal at New Mexico as a spinoff of wiretaps involving gambling. The NABC board feels that the atmosphere now is perfect for another point-shaving scandal because of the appeal of college basketball, the big television contracts it generates and the fat salaries and side benefits accured by the coaches.

Yet, the people responsible for the surge -- the players -- do not share in the revenues they generate. In fact, they make less now, since the $15 per month laundry money was eliminated from their grants in aid. Tex Winter, the Long Beach State coach and an NABC director, calls the situation "a powder keg."

Monday's speaker is Francis Mullen Jr. of Washington, D.C., assistant director of the FBI's Division of Criminal Investigation. He was lined up by St.John's Coach Lou Carnesecca who, among many, believes taht majority of today's college coaches are not fully aware of the severity of the point-shaving possibilities.

There wil be a question-and-answer period afterwards.

Darrell Griffith, Louisville's star guard, has dedicated winning the NCAA basketball championship to Jerry Stringer, a friend of his who is fighting cancer in Louisville.

Stringer, formerly the team manager at both Louisville and Male High School where Griffith played, was Griffith's next-door neighbor for the past three years. Griffith revealed his friend's plight during a pep rally before the Cardinals came here.

"He's fighting against cancer," said Griffith today. "It's in the third quarter and he's losing. I'd like to do something for him, so I dedicated winning this tournament to him."

The NCAA is licking its chops over the day soon when nmegotiations begin for the new television contract for the NCAA tournament. Apparently both NBC, which currently holds it, and ABC are going to bid.

This is the first year of a two-year contract. NBC is paying $8.5 million for rights to the tournament this year and will pay $10 million next year, a 100 percent increase over the 1979 tournament.

No major rules changes are expected when the basketball rules committee meets here Tuesday and Wednesday. In a survey of coaches, officials and administrators, the vote was strongly against any kind of shot clock.

With more than 800 coaches voting, the margin was 4 1/2 to 1 against a 30-second clock, 6 to 1 against a 45-second clock, 9 to 1 against a 60-second clock and 3 1/2 to 1 against a 45-second clock for the game's first 35 minutes, with unlimited possession time the rest of the game.

The survey also showed a 450-416 magin in favor of eliminating the technical foul when a dunker grabs the rim after being fouled during the dunk. This season anyone grabbing the rim for any reason during a dunk was committing a technical.

Joe Harrington, the former Maryland assistant and currently head coach at Hofstra, has decided not to pursue the vacant George Mason job, even though he likes the Washington area and his wife, an assistant state's attorney in Montgomery County, still lives there.

The prospects of Harrington leaving a program that needs stabilization gave him leverage to get better practice conditions and the right to make his own schedule. Last year, Hofstra played only nine games at home.

Meanwhile, George Mason will stop taking applications for coaches on Monday. About 60 candidates have applied thus far, including Jack Kvancz of Catholic University, Wil Jones of the University of the District of Columbia and Joe Dean Davidson of Dunbar High. Bob Hamilton, the recently fired Navy coach, has not applied, Athletic Director Bob Epskamp said. Epskamp said he plans to reduce the field to no more than six candidates within a week and begin interviews. He said there is no front-runner for the job, although Kvancz's name has been mentioned prominently.
