Tyrese Maxey and Kyle Lowry spear-headed a valiant effort to bring the Sixers back in the second half, but they fell short of a major comeback in a 110-96 defeat.

The Sixers' moves ahead of Thursday afternoon's trade deadline spoke muffledly, so president of basketball operations Daryl Morey did the talking ahead of Friday's loss to the Atlanta Hawks.
