MIN won't want Perk now that they locked up Darko.
I could see something like Sheed and S&T Nate on a short (two year or one year deal) with cash and a future first as the only way they'd even think of it. They basically get a free trial of Nate Robinson and out of the contract, plus a future first to (hopefully replace the talent.) They might also be open to taking BBD, but he's 800k short of being enough to trade for Jefferson.
They don't want to pay Al Jefferson 42 million over for the next three years and I think they'll prefer an exit that saves money or saves face, if only one of the two is available.
