Its swirling around....
Magic was also interested in Rozier for Ibaka potential trade the last time.
I believe the rumors the Magic are interested in signing Isaiah Thomas but only as a plan "b". So team is not in a rush to make this move.
Getting back to topic... if Magic want Rozier it would be for Bamba. Celts can add something extra .... there would be nothing else from their roster/picks that I would want.
