Cleveland Cavaliers forward Jae Crowder did not leave the Boston Celtics on his own terms, and as such, he feels he should be treated fairly Wednesday in his return to TD Garden. Crowder joined Isaiah Thomas and Ante Zizic in the Celtics-Cavs trade that landed Kyrie Irving in Boston, and prior to his departure, the veteran forward had been one of the key pieces in the Celtics’ rapid rebuild toward prominence in the Eastern Conference. And as a result, Crowder told The Boston Globe’s Gary Washburn on Tuesday he deserves some cheering in his return to Boston.
