Navy's Leo Williams, dethroned as IC4A high-jump champion a week ago, will try to rebound by capturing his third straight title in the NCAA Indoor Track and Field Championships, scheduled tonight and Saturday in Pontiac, Mich.

Williams was beaten in the IC4A by Bermudan Nick Saunders of Boston University, who cleared 7-6 1/2 and will be in the NCAA field. Another contender is Mike Pascuzzo of Maryland.

George Mason's mile relay team of Tommy Lovelace, Reggie Henderson, Ron George and John Parker is seeded second behind Southern Methodist. Henderson is one of the favorites in the 400 meters and Mike Scudieri will compete in the triple jump.

Miler Kevin King is Georgetown's lone representative, while pole vaulter William Butler and 35-pound weight thrower Alan Baginski join Pascuzzo in Maryland's colors.

Kris Kristoffersen, the Terrapins' fine middle-distance runner, had earned a berth in the two-mile, but he recently was struck by a car in College Park and suffered a broken ankle and a dislocated shoulder.

A women's meet will be run concurrently for the first time and Maryland qualified three competitors--long jumpers Tomi Rucker and Tamela Penny and miler Carolyn Forde. The only other area woman in the competition is Howard's DaChanta Phillips in the 60-yard dash.

Major changes dictated by the desire for a streamlined television package have created considerable dissatisfaction with the administration of the NCAA indoor meet. For one thing, the three-mile and distance-medley relay were thrown out this year, despite an 84-0 vote in opposition by collegiate track coaches.

Far more divisive was the move to limit competitors to the 12 fastest relay teams and the top 20 qualifiers in all other events except sprints and hurdles, which accepted 24.

Indoor facilities vary widely and teams that were able to run on outsized tracks like the ones in Boston and Johnson City, Tenn., earned the better times and most of the qualifying berths.

Opposition to the present situation, while universal, was strongest locally at Howard, which saw its women's mile-relay team, 600 runner Karen Gascoigne and long-jumper Brenda Bailey victimized by the quota system after all had bettered the qualifying standards.

"It's just not fair to our student athletes to tell them they will get a certain reward for meeting a particular standard, then say, 'You can't go because you didn't meet a super standard,' " said Howard Coach Bill Moultrie.
