As when we gave up Al Jefferson for KG, Jared Sullinger will have to be given up for Kevin Love. But Kevin Love high risk - high reward.
Me, I'd go Sully, Jeff Green, Faverani, Brooklyn's 2014 1st and our 2015 first for Love and Robbie Hummel (so we get a replacement SF).
So for the T-Wolves, they get an up and coming PF, a starter level SF, a legitimate backup Center and two first rounders.
For us, we get top 20 player, high reward.
The gamble part comes with his contract, it's a bit worrisome as we don't know if he would like to stay in Boston but, we have a year to figure it out. If we get Kevin Love to love (no pun) playing here, he might stay and we'll have a core moving forward of. If all indications are he's leaving, then trade him next season and acquire assets. We may not get back the same value as Green and Sully for him, but that's the high risk we need to take if we trade for Love.
