Skeets Nehemiah and Greg (Fly) Robertson are scheduled for quadruple duty at Philadelphia's Franklin Field today and tomorrow, as Maryland exerts its troops to the fullest in a bid for a third straight IC4A outdoor track and field championship.

Nehemiah will contest the 110-meter high hurdles, where he is an overwhelming favorite; the 100 meters the 400-meter relay and the 1,600-meter relay. Robertson is listed for the 400-meter intermediate hurdles and the highs, in both of which he is defending champion, and both relays.

Assuming success along the way, that means each athlete will run 10 times in two days. It will be necessary, if the Terrapins are to fight off the challenge of powerful Villanova. The Wildcats are working to output, too, with Don Paige attempting the difficult 800-1,500 double.

"They want to win the meet very badly or they wouldn't try that," said Maryland Coach Frank Costello. "On the other hand, if they thought they had the meet in the bag, they wouldn't try it, either. There aren't too many people in the country who could do it, but Paige can. And they could put it out of range if they go 1-2-3 in the quarter and 1-2-3 in the half.

"We've got the personnel to score enough points to win it, but Villanova's points are more stable. If I were a betting man, I'd put my money on Villanova. But there's no doubt in my mind that we can win it."

Maryland's Bob Calhoun, a double winner in the indoor IC4A otherwise dominated by Villanova, will contest the 100 meters and long jump, as well as leading off the 400-meter relay.

Another key to the Terrapins' chances is Ian Yyka, the shot put defender who last week had an excellent toss of 62 feet 5 1/2 inches. Pyka will also be a threat in the discus as he tries to make up for the points lost by the transfer of 1977 champion Scott Hersh to Arizona State.

Dennis Ivory defends his long jump crown and figures to score in the triple jump. Brian Melly, with a seasonal best of 7-3, can win the high jump if Fairleigh Dickinson's Franklin Jacobs has an off day. Other Terrapins with point potential are Bo Kent, long jump; Andre Lancaster, 200; Mark Fields, 400, and decathlete Dave Dubyoski, javelin.

Besides maximum output from its own contingent, Maryland needs help from others in the 75-school field, particularly by cutting into Villanova's domination of the running events.

Finals are scheduled today in the long jump, shot put, hammer and 10,000 meters. The other 16 events will be decided tomorrow. Competition begins each day at noon.
