Cleveland needs better shooting and scoring from their wings as well as a bench PG. They’re getting all of that and more (2 firsts and 2 seconds) for DG and JA (both who are on the move this offseason). I’d expect BI to play PF for Cleveland (which is a much better fit for his play style), Johnson would start at SF, Strus at SG and Mitchell at PG. Devonte would be a fine addition to Cleveland’s deep bench.
NOP needs a real C to play alongside Zion. Jarrett has made it work with Mobley for years so there shouldn’t be any issues there. The Pels have a plethora of picks and CJs contract to address the PG position as well (maybe Dejonte or Trae could be an option).
SAS needs a PG to play alongside Wemby and to feed him the ball. DG is a more than capable scorer and a great passer of the basketball. San Antonio would gladly add him to their young roster.
