It seems like the remote possibility of KD coming to Boston is growing even more remote with each passing day, and Danny Ainge is obviously smart enough to have contingency plans. I would definitely give Whiteside the max as he's young and put up great numbers 2 years in a row. If we got him and then either kept our pick if it's top two, or traded it for Butler, then I think we would be a much improved team with a chance to get that much better in the 2017 FA class (which has much more quantity and quality than this years).
Let's not get greedy - if we can get KD then great, but in the likely event we can't let's not act like a stud a la Whiteside is beneath us!
