The Bulls acquire Siakam, who is the perfect stud power forward for them who can give them another lethal scorer and more importantly, a big and mobile defender. A starting 5 of Lonzo, Lavine, Derozan, Siakam, and Vucevic would be arguably the most complete in the league and make them championship contenders in my eyes.
The Raptors receive a slew of assets in return for Siakam. Bamba is already an elite rim protecter and has shown flashes of unlimited potential while White is a young combo guard who can put the ball in the net. Brown Jr is a great young defender, and they get three first-round picks to sweeten the deal even further.
The Magic finally trade Bamba and give him a chance to thrive somewhere else. In return, they get a fantastic young wing with star potential in Williams. He has already shown flashes as an efficient scorer with a smooth jumper who can finish at the rim. Then there is his defense, which is already elite at 20 years old.
