McKinley's all-America basketball forward William (Doons) Martin ended weeks of speculation yesterday when he announced he will attend Georgetown University this fall.

The 6-foot-6 1/2, 190-pound senior said he narrowed his choices of schools to GU, Maryland, Pittsburgh, Oregon State and Howard before deciding on the Hoyas. Martin denied Maryland, which had tried hard to recruit him.

"I carefully weighed all the facts, academics and athletics, and decided I would be comfortable at Georgetown," Martin said at a morning press conference at McKinley. "I feel John Thompson is a good coach and can help me accomplish my athletic and academic goals. I wanted to make this official now so I can get back to my studies and have some fun the rest of this basketball season."

Martin, an all-Met last year, said Thompson's manner, and talks with one of his best friends, Gene Smith, a former McKinley player now at Georgetown, were major factors in his decision. Asked if the decision by all-America Pat Ewing of Cambridge, Mass., to attend Georgetown had anything to do with his choice, Martin laughed and said, "Not really, but he's a big plus."

Martin, an excellent inside player with a good, medium-range jump shot, is averaging 20.1 points and 14 rebounds a game for the 20th-ranked 12-7 Trainers. Last year, he averaged 18 points and 14 rebounds. Martin also started as a sophomore, averaging eight points and eight rebounds.

More than 300 schools showed interest in him and, according to McKinley co-head Coach Lafayette Mosley, "He listened to a lot of people before making his choice."

"He weighed everything and I think he made the right choice for him," said Mosley, who has worked closely with Martin for three years.

Martin, who plans to major in business, hopes to play big forward for the Hoyas. Martin said that should the Hoyas also sign Dunbar's all-America Anthony Jones, the team would be that much stronger.
