Mavs - Mavs receives a former Dpoy that you can partner up with Luka then Mavs also got 2 role players with size and length that can also help the defensive end, Kornet is a big man that can protect the rim well while Blake is a decent help defender. Mavs need to surround Luka with defenders and that's that. If they do that I am sure they can be a top-seeded team.

Celtics - I don't know if Celtics will accept since they are in a contending phase and they are good to go for the next 5 years but value wise and to make it interesting at least, Kyrie is that player that can boost your offense, with Rob Williams coming back from an injury I don't think the Celtics would be that kind of team to be horrible on defense because one of their core guys in defense is gone they still do have players like Tatum, brown, rob, Horford and grant so I am not worried about their defense collapsing if smart is gone. I don't know if the Celtics fanbase would welcome Kyrie, but a trio of Brown, Tatum, and Kyrie is already to insane to think about. But again, I don't think Celtics would accept and I am only doing this for the Mavs but not gonna lie, I don't see this trade as a bad trade as in bad.
