Bulls get Jerami Grant, who is the perfect player for them. He is a defensive stud and can create for himself on offense. With Grant, the Bulls have one of the best starting 5s in the league. They lose a lot of their depth and young talent, but become true championship contenders in my eyes.
The Pistons get a slew of young talent for Jerami Grant, including Patrick Williams, Onyeka Okongwu, and Troy Brown Jr. along with a plethora of picks. Williams is a fantastic young two-way forward who can essentially take Grants place in the lineup. Okongwu is a potential defensive stud and Brown Jr. is a quality young two-way wing. They get an assortment of picks to top it off, including two first (one being OKC's pick from Atlanta) and two second round picks.
Hawks get Coby White, who is the scoring combo guard they have always needed. While they already have Lou Williams, he is 34 and on his way out. White gives them another ball handler on the roster who can give Trae Young some rest. They also get an upgraded backup center in Tony Bradley.
