Well the Magic only have Miller to give up unless someone wants Garrity.
If the Grizz get Dunleavy there would be no point to even show interest in Miller because they would have their (2,3) spots covered with shooters (Dickerson,Dunleavy)
Maybe your #18 and Miller for Swift if the Grizz get Butler.
(seems harsh but I think the Magic will do more then expected to get a big man)
