Why this is the "Ideal Trade": The Point Guard Trade: The Cavs trade Darius Garland for another young All-Star point guard, LaMelo Ball.
Complementarity: Ball, who is taller (6'7") and excels as a secondary playmaker, complements Donovan Mitchell better than any other smaller guard. He increases the team's size and rebounding ability.
For the Hornets: Charlotte receives Darius Garland for a potential rebuild or for the Garland-Ball duo. The addition of a draft pick makes the offer very attractive for a team building up young talent.
