Stephon Marbury

The Celtics have historically been willing to bring in aging veterans on low-risk deals. It started in the 80s with an over-the-hill — but still serviceable — Bill Walton and included several other former All-Stars. Marbury was a legitimate star during his prime, but he bounced around the league a ton during his early years and never landed in a solid situation.
Following his disastrous run with the Knicks, Marbury attempted to make one more run at a championship. A Boston team in need of guard play took a chance on ‘Starbury’ in 2009. The two-time All-Star proceeded to have the worst stretch of his career, averaging 3.8 PPG in 23 games with Boston. Marbury’s poor play pushed him to begin a new career in China, where he flourished as one of the more popular and prominent players in the CBA for several more years.
