Patrick Ewing of Georgetown was one of four unanimous choices named to the Associated Press all-America basketball team and Len Bias of Maryland, who made the AP's second team, was chosen as Atlantic Coast Conference player of the year.

Ewing, Chris Mullin of St. John's and Wayman Tisdale of Oklahoma, all members of the gold medal-winning U.S. Olympic basketball team last summer, were unanimous choices to the AP's first team, along with Keith Lee of Memphis State. The fifth member of the first team was Wichita State's Xavier McDaniel, a 6-foot-7 senior who averaged 27.4 points and led the nation with 15.0 rebounds a game. Ewing and Tisdale, the only junior on the first team, were named for the third straight season.

Bias, a 6-8 junior who led the ACC in scoring, was part of a second team that included two other ACC players: Duke guard Johnny Dawkins and Georgia Tech guard Mark Price. Southern Methodist center Jon Koncak and Kentucky forward Kenny Walker also made the second team. The AP third team included Syracuse guard Dwayne (Pearl) Washington, Michigan State guard Sam Vincent, Michigan center Roy Tarpley, Oregon State forward A.C. Green and Loyola of Chicago's Alfredrick Hughes, tied with McDaniel as the leading scorer in the country.

Bias was chosen for the ACC award by members of the Atlantic Coast Sportswriters Association, beating out N.C. State's Lorenzo Charles with 54 of the 127 votes cast. Charles got 35 votes and Price 28.

"Before the season started, my goals were to work as hard as I could, help the team win and make all-America," Bias said. "Now, it looks like I'm going to reach some of those goals.

"I tried not to think about the player-of-the-year thing because I didn't want to get too excited about it and then be let down if I didn't get it. I think to win it in this conference is really a compliment. It's like getting a nice present."

Maryland Coach Lefty Driesell, who changed Bias' jump shot, getting him to shoot the ball at the top of his jump instead of on the way up, also was pleased. "Len showed the most improvement from his freshman year to this year than any player I have ever coached," he said. "He's one of the best. He's a complete player, a scorer and a rebounder and he plays good defense. The height he reaches on his jump shot is unreal."

Bias, who averaged 19.1 points and 6.7 rebounds a game, is the first Maryland player to win the award since Albert King in 1980.

Ewing, who has led Georgetown to a 30-2 record in defense of its national title, averaged 14.6 points a game, 9.7 rebounds and almost four blocked shots a game. Mullin, the all-time leading scorer at St. John's with 2,350 points, averaged 19.5 points a game and led the Redmen to the Big East regular-season title. On Sunday, Mullin was named over Ewing as the winner of the John Wooden Award as national player of the year.

Tisdale, who is 6-9, led Oklahoma to a 28-5 record, averaging 25.5 points a game. He has scored 2,570 points in only three seasons and is already the Big Eight's all-time leading scorer. Many people expect him to pass up his senior year to turn pro.

Lee, a slender 6-10, averaged 20.4 points and 9.6 rebounds a game this season, leading Memphis State (27-3) to the Metro Conference tournament and regular-season titles.
