This game showed how much they've been hurt by first the Fultz fiasco, then the Zhaire Smith injury.
Smith was drafted for the Celtics, an ultra athletic guard who could shadow Irving and make him work hard, then be able to bring Reddick off the bench without exposing him to gross defensive mismatches.
Sixers simply didn't have anyone to guard Irving or Rozier.
Milton can score off the bench, but I'm not sure he's quick enough to cover top guards.
He is back after the broken finger, and might get some PT before the playoffs.
