Andrew Bynum is officially a member of the Cleveland Cavaliers. The Cavaliers only guaranteed Bynum $6 million in the first year of the deal, but he could earn an additional $6 million through performance incentives. Bynum sat out the entire 2012-2013 season with Philadelphia because of knee injuries, but said he will be medically cleared to practice by the start of training camp. Cleveland holds a $12 million team option for the second season. He underwent surgery on both knees in March.
