Sooooo, there's this:
Boston Celtics close to signing enigmatic big man JaVale McGee, multiple sources told ESPN. Deal with be through next season.source: Jeff Goodman, ESPN
McGee, 27, averaged just over 11 points, 8 rebounds and 2 blocks a game in 2011/12 with the Washington Wizards. Since then he had a mostly unsuccessful stint in Denver, and a cup of coffee with the Philadelphia 76ers before being bought out. He is also the absolute worst. #PrayforBradStevens
UPDATE: Danny Ainge has confirmed the report during his appearance with 'Toucher & Rich'
