Cleveland???
How did this turn into a thread about Cleveland and not Minnesota?
Cleveland is not making a deal, they are drafting #1 and #4. They certainly will not make a deal with an East Coast team, for pieces they do not need.
Minnesota might make a deal, in particular for Billups, since they have issues at PG and want a veteran, not another young talent project (they already have several of those).
I make the deal, not so much for Kyrie Irving (who I do not expect to be available at #2) nor for Derrick Williams (who we do not need unless he can play SG), but for Enes Kanter, who could become a dominant top-five center in a few years.
I still get Dalembert so that we can develop Kanter properly, and I try not to trade the #17 pick as part of the deal with Minnesota, so that I can still draft Faried or a mid-level PG. If Minnesota insists on the #17 pick then I try to get one of their young PGs as part of the deal.
Even if Cleveland were willing to deal (which they will not be), Kanter is probably not available at #4, so you are talking Brandon Knight or Kemba Walker. Nice players, but not a potentially dominant center (which is worth giving up Billups for). Otherwise, why not just draft a backup PG, and wait for CP3.
