Why trade him for the Hornets' unprotected first? Just trade him straight up for AD!
Both deals are about as likely to happen
Heck, why not BOTH the pick and AD?
If Charlotte makes the playoffs again (likely given how weak the East is), they could have a first round pick in the 20's. Rozier was the 16th pick a couple years ago. While he has shown flashes, he really hasn't done that much.
That being said, he had IT and Marcus Smart in front of him. Now he has Kyrie ahead of him.
If The Hornets wanted a backup PG, they could do worse than Rozier.
I don't necessarily see CHA trading a first for Rozier, but its not a comparable trade to anything including Anthony Davis.
