When I played for Garfield Heights in the early 60's, the only truly famous basketball player that showed up was Ralph Crosthwaite (from Saturday's opponent, WKU)
http://www.hilltopperhaven.com/legends/crosthwaite.html . He moved into the area while trying out for the Cleveland Pipers after failing to make the Celtics. I worked out with him during the summer. He didn't make the Pipers either (not my fault). Otherwise, the only "famous" players that showed up were alumni that played (or were playing) in college.
