Maryland, criticized for scheduling patsies and playing so many home games, is beefing up its basketball schedule over the next three seasons.

The new competition includes a home-and-home series with Louisville.

Maryland also will renew a home-and-home series with Penn State, will play Georgetown again after a one-year lapse, will continue the Notre Dame series for three more years and will play Pittsburgh on the road, associate athletic director Al Hanlon said yesterday.

Such teams as Ball State, Appalachian State and Richmond are missing from next year's schedule, which still includes two open dates.

Under terms of the NCAA basketball package with NBC, now in its second year, the addition of the Louisville series and the continuation of the Notre Dame series, now set for the third Saturday each January, should add considerable revenue to the Maryland athletic department and give the Terps better national exposure.

The Louisville series starts in the 1978-79 season. Navy agreed to drop its 1978-79 game so the Terps could schedule Lousville, Hanlon said.

Assistant athletic director Russ Potts, whose duties include television and radio commitments, said that Maryland receives about $50,000 for each nationally televised game and keeps about $25,000 after splitting with the other Atlantic Coast Conference schools.
