More than the Jays, replacing Kyrie with Kemba has been huge for this team. On court chemistry has been noticeably better and I gotta believe it starts when your best player is willing to give up shots and the limelight to others.
Also, with less mouths to feed, I gotta believe losing Horford, Morris and Rozier has helped.
I also prefer Kemba to Kyrie, but I think people gloss over this second point far too much. It's hard to argue that Horford being on the team was a net negative for Brown and Tatum, but Morris and Rozier clearly were me-first guys who took way too many shots and unnecessary playing time away from them.
Don't get me wrong, I didn't hate Morris and Rozier while they were here, I just hated them for this team. Honestly, if they weren't on the 18-19 team, I believe Jaylen and Hayward would have been far more comfortable which likely would have led to Kyrie being more comfortable and he would probably be our starting PG today.
I am not unhappy with the way things have worked out - this team is truly a joy to watch - but a team with a happy Kyrie, AD, Horford, Brown, and Hayward would also be pretty dominant.
