I don't know what the direction is in Chicago. Sure, they're shopping Lavine, but what is the market for him? Almost everyone on Chicago's roster right now is best with the ball in their hands. The sorts of players Giddey fits best with are in high demand, and I don't know where Chicago gets a roster full of them in one off-season.
He'd be a great fit in Orlando, where there are a lot of guys who can shoot, create and defend, but no real full-time orchestrator. He fits their timeline, and you don't have to envision a franchise overhaul to see him playing a successful role there.
The Spurs, people have already identified as a good spot, I think Miami or New Orleans could be decent. And if he's going to a rebuilding team, I'd like to see him in Utah where I at least understand how they get to be good again.
