The way Sullinger has been going lately, he could be the best main piece Minnesota get offered for K-Love in a trade next year if Minnesota decide to trade him (should Love not sign a contract extension).
Boston have a good case as the frontrunner to land Kevin Love.
I don't think Boston would need to give up 2 first rounders either. I think one, not even a high one, one late first + Sully could be enough to get it done.
