Patrick Ewing, Georgetown's 7-foot sophomore center, was named to the Associated Press first-team all-America squad yesterday and Virginia's Ralph Sampson was selected for the third straight year.

Ewing's selection confirmed what the statistics and the Hoyas' opponents have been saying all season.

Boston College Coach Gary Williams recently put it this way: "Patrick is awesome. He can do so many things."

This season, Ewing has averaged 17.4 points and 10.2 rebounds per game and has blocked 104 shots, seventh best in the nation.

Joining Ewing and Sampson on the first team are Tennessee senior forward Dale Ellis, North Carolina sophomore forward Michael Jordan and Oklahoma forward Wayman Tisdale, the first freshman to be named.

Georgetown (21-9) left yesterday for Louisville, where the Hoyas will play either Xavier or Alcorn State in the NCAA Midwest Regional Friday night.

This season, two factors have been necessary for Georgetown to win: first, the Hoyas must get the ball inside to Ewing, who is often surrounded by two or three players; second, Ewing must avoid fouling out.

"I think we have been more patient passing the ball recently," Ewing said. "I think they (teammates) have been doing a much better job of getting me the ball."

Perhaps the statistic that best represents Ewing's value is this: in games in which Ewing has fouled out this season, Georgetown has a 1-5 record; in two years, Georgetown is 3-8 when Ewing has fouled out.

"I try not to pick up stupid fouls on the perimeter now," said Ewing.

Sampson, a 7-foot-4 center, has averaged 19.1 points and 11.7 rebounds and has blocked 91 shots for Virginia in a 27-4 year.

Ellis is a 6-foot-7 forward who scored 23 points, had 6.7 rebounds per game in the Southeastern Conference. He leads Tennessee with a 60.2 shooting percentage. Jordan is a silky 6-5 sophomore, whose many talents and success in the clutch have prompted Carolina fans to call him "Miracle Michael." This season, Jordan has averaged 20.1 points per game, shooting 54 percent from the field, and has made 77 steals.

Tisdale of Oklahoma is a 6-9 forward who led the Big Eight in scoring (25.1 points), blocked shots (76) and rebounding (10.2).
