Recently, players from Ball Up Streetball joined EXTRA TV for a day termed “EXTRApalooza” at The Grove in Los Angeles, CA. And at an otherwise uneventful sunny gathering, EXTA host Maria Menounos, a big Boston Celtics fan and courtside regular, allowed Ball Up’s Air Up There to use her as a dunk contest-like prop. Something tells us her many friends on the Celtics would not be pleased with her defensive effort.
