Those are superstar franchise player stats. Just because Chicago might trade him doesn't mske him a non-superstar. Melo, CP3 and Love got traded. Dwight Howard was traded. Superstars/franchise players get traded. It doesn't preclude them from being superstars.
I would send Crowder, 2017 Brooklyn 1st, Memphis 1st, Yabusele and filler.
IT/Smart/Rozier
Bradley/Green
Butler/Brown
Horford/Jerebko
Johnson/KO
Thats a great 11 man rotation worthy of an ECF appearance. If Zizic can come over and play as well as he has overseas and/or we trade picks and Rozier for Noel even better. The Celtics would be one of the best offenses and defenses in the league.
