All he did was pick up money and traded a pick this year for a future first and again, that's not what they need. They need vets with talent and came away with Miller(a guy that's old and injured) and money.
To me, trading the 20th pick in a bad draft for a future #1 in a better draft is a sound proposition, regardless of what needs are. Since the Twolves probably couldn't have met their needs this year regardless, getting a future asset is a good move.
The Twolves are no worse in the present, and have a future asset. I don't see why that's a bad thing. I mean, if before this draft Danny had traded the #25 pick for a future #1 and cash, people would be singing his praises. However, since Kahn did the exact same thing, it must be an idiotic move, since Kahn is an idiot.
