The suns will get the depth that they are lacking alongside Booker. The Mavs will get a 3&D guy in O'neal and also getting KAT joining AD to dominate the paint, creating a super team with Kyrie. AND will still be able to keep their First (FLAGG). The knicks will get KD in return and some decent role players with a new athletic starting Center in Richards.
Potential Starters:
SUNS: Booker, Bridges, Dunn, Washington, Gafford
MAVS: Kyrie, O'neal, Flagg?, AD, KAT
Knicks: Brunson, Hart, KD, Anunoby, Richards/Robinson
