It’s not losing Horford per se as it is not having 5 legit guys who should have the ball in their hands.
Last year: Kyrie, Brown, Tatum, Hayward, Horford
This year: Kemba, Brown, Tatum, Hayward
Roles are definitely more defined vs last year and losing Rozier/Morris also helped redistribute the shots (because our role players this year barely want to shoot it, save for Smart and Carsen)
