I think he's the best fit for us. I love MKG, but we need shooting more than anything, and that's obviously his biggest flaw. And Miller is too inconsistent. I would still take him, if our pick is between 8-12 though. But if destiny likes us again, and we get the #3 pick, we take Barnes. I wouldn't even have to think about it.
Incidentally, I no longer feel Barnes will go #3. Teams I've talked to are saying he's around 4-6 depending on who's picking where.
