Okc: they already have a ton of guards Isaiah Joe Caruso shai Ajay Jared Aaron Nikola topic etc might as well trade one free a few million dollars. They get a potential breakout player in rishicher in a position needing more depth and a good center to play backup and make up for the potential loss in hartenstein
Hawks: they avoid needing to get CJ back and get the point guard of there future who will make the perimeter defense even stronger and on a cheap deal he also has good ball handling and a great assist turnover ration and adds height at the 1. They also get a good backup 3/4 in Kendrick who is a vet and can give good minutes. Also they get a 1st which will give them 3 1sts to potentially trade up or get a good center.
