I doubt if anyone is taking Dieng's deal (which doesn't end until 2021), especially the Heat, who will be paying a ton of luxury tax this year for a team with no chance of winning, even with Butler.
I can construct credible packages for a dozen teams, including many from wannabe playoff teams in the EC, where I assume the Wolves will want to send Butler.
Milwaukee: Snell, Henson, Teletovic. Pick any two
Philadelphis: Covington and Bayless
Toronto: straight up for Ibaka. Or Danny Green and C.J. Miles
Washington: Austin Rivers and Markieff Morris
Brooklyn: DeMarre Carroll and Caris LeVert
Indiana: Evans and Bogdanovic
Cleveland: Jordan Clarkson, Kyle Korver
Any of these deals could be sweetened with picks, if necessary.
