The Capitals don't have enough trouble on the ice, owner Abe Pellin and club are being sued for $400,000 in federal court. Baltimore. David W. Brewer of West Hartford, Conn., says he scouted 155 games for the Caps, filing detailed reports-and sending detailed monthly expense statements-and was reimbursed only $649.50.

Brewer claims he had a non-written agreement with the Washington hockey club to be its special assignment scout for the 1976-77 season, furnishing assessments of upcoming opponents and of players the Caps might be interested in acquiring. He says he was to be paid "a reasonable salary" at season's end plus expenses; when it didn't come, he quit in November 1977. General Manager Max McNab, limiting comment "because the case is in the courts," maintains that "everyone with authorization has been paid in full."

Another All-America footballer from the area: first team on the Kodak Division II squad selected by the American Football Coaches Association, and second team by Associated Press, he's Ed McGlasson of Potomac, who prepped at Bullis and made it big at center for Youngstown State. YSU says that at 6-4. 240, McGlasson is the apple of some pro scouts' eyes; made offensive lineman of the year in the Mid-Continent Conference.

OLD NBA players never-. Head coach of the women's basketball team at his alma mater Mount St. Mary's this year is Fred Carter, the Baltimore Bullet they used to called Mad Dog when he was Earl Monroe's sweet-shooting sidekick. And his Mounties at last count stood 7-1 . . . Officiating in the Western Basketball Association (where the Montana Sky featuring Brad Davis has sunk to 2-15): 6-11 and hefty Dale Schlueter, the longtime journeyman center in the big league. Who's argue with him?
