I don't mind Rozier with the 16th pick. In the event AB or Turner gets dealt this season he will be at the least an insurance policy.
He's a solid ball handler and just needs development in other areas.
My concern is that Ainge will not trade either of those guys because other teams won't give him significant assets for either, i.e. "Their value to us is greater than it is to other teams."
Bradley I think would fetch a mid to late first and salary fodder, Turner would be a pure salary dump.
