Your points are well-taken. Lee and Amir would obviously be very good options in terms of salary match, but they also aren't young guys you'd look to build around. If you're looking for something similar, would you choose Brook Lopez over Lee? Faried over Amir? What about someone like Favors?
I think there would likely be other enticing packages out there that would get hard looks. Again, though, I would be thrilled to get Melo (and I've always disliked Melo from a bball standpoint).
