I think Korver showed real effort on defence in the series against us. I think Brad can put him in situations to succeed. Offensively he obviously adds a dimension we don't currently have, running off screens like a gazelle the whole game.
I think it depends on what happens with Smart. If he does end up elsewhere, although unlikely, then I could see it happening. If he stays then I don't see a spot for Korver in the rotation.
