With St. Basil's Cathedral in the background, Arvidas Sabonis, once the mainstay of the Soviet national team, blocks a shot by former NBA star Dan Roundfield. A team from the U.S., representing the National Basketball Retired Players Association, took on a team largely made up of players from the U.S.S.R.'s 1988 gold-medal-winning Olympic team last week in what is believed to be the first basketball game ever played in Red Square. More than 30,000 spectators watched the game, won 94-78 by the Russian stars, which was dedicated to the Allied victory over Germany in World War II. Among the players on the Retired team, coached by Oscar Robertson and Dave DeBusschere, were Adrian Dantley, Walter Davis, Cedric Maxwell, Trent Tucker and Darrell Walker. The team is also scheduled to play games in Europe and China to raise money for NBA old-timers.
