Following in the (size 23) footsteps of former Celtics big man Robert Parish, C’s great Jo Jo White is selling some of the valuable keepsakes he accumulated during his Hall of Fame career. White is auctioning the championship ring he received after the Celts won the 2008 NBA title, as well as the 1974 and 1976 championship rings he was given as replacements when the originals were lost. (A seven-time NBA All-Star, White spent a decade with the C’s, winning two titles and having his No. 10 retired to the rafters. These days, White, 69, is director of special projects in the team’s community relations department.) “We are extremely pleased to be offering many of Jo Jo’s coveted basketball heirlooms,” David Kohler, president of SCP Auctions, said in a statement. Other items on the auction block include several warm-up and game-used uniforms, White’s 1976 NBA Finals MVP digital wristwatch, two College All-American plaques from Kansas, his Kansas Sports Hall of Fame induction plaque, and his 1976 and 1977 NBA All-Star Game plaques. A few years ago, Parish made news when he auctioned his 1981 NBA championship ring for $45,578.Names can be reached at firstname.lastname@example.org. Follow Mark Shanahan on Twitter @MarkAShanahan.
