An old friend reportedly could end up with the Boston Celtics. Joe Johnson was one of the many casualties of the Cleveland Cavaliers’ roster blowup before Thursday’s NBA Trade deadline. Shortly after sending Isaiah Thomas to the Los Angeles Lakers, the Cavs sent forward Jae Crowder and guard Derrick Rose to the Utah Jazz for guard Rodney Hood in a three-team deal with the Sacramento Kings. The Jazz sent Johnson to the Kings, the Cavs sent forward Iman Shumpert to the Kings, and Sacramento sent guard George Hill to Cleveland. Got it? Good. So, where do the Celtics come in? Well, Sacramento is expected to buy out Johnson, and the C’s are expected to be among the teams involved in an “intense” bidding war for the veteran guard’s services, according to NBC Sports Boston’s A. Sherrod Blakely.
