I expect something to happen. I don't know what exactly, but I expect something. We could take Dunn, but I'd expect a follow-up trade. We can't roll into next season with 7 guards and 7 draft picks. Really high probability we do something tonight. Especially if the rumors are true and Okafor and Noel are available.
I agree, and to be honest if we do take Dunn I would expect we will keep him and move Smart, Rozier or Bradley - with Smart being most likely to go.
Dunn has such an incredibly high ceiling that it doesn't make much sense to move him unless you're going to get a monster of a return. Makes a lot more sense to move Smart, since he is essentially a poor man's Dunn and likely has more trade value then Rozier.
Unlikely that Bradley would be the guy moved, because just in case Dunn doesn't work out, Danny would probably want to make sure he has a solid and proven veteran shooter at the SG spot.
