I think this trade makes sense for both sides. For the Bucks, Herro is expiring and they already have a lot of guards, so I don’t really see why they’d keep him. They get Duncan Robinson for shooting, Ron Holland as a young guy with upside, and a 1st and 2 srp.

For the Pistons, they need someone next to Cade who can actually create his own shot and take some pressure off him. Herro would give them another scorer and a legit offensive option next to Cade.
