Remember when we could have drafted this guy? Remember when passing on him was a huge hullabaloo? Proof of Kahn's ineptitude? (Kahn didn't need more proof of that at this point). We can trade Derrick Williams for him right now and WIIIIINNNNNNN!!!!!!!
OK, ok, so I'm just trying to be a little inflammatory. But seriously, this trade actually does work. The honest truth, however, is that if I'm the Wolves there is no way in Hades that I would even consider this trade. If you are sour on DWill, then I would expect you would be doubly as sour on Cousins. Why? DWill hasn't pout, doesn't get ejected or suspended. He's shown that he can take coaching (improved defense), and is potentially showing that he's getting better at understanding which shots to take and which ones not to.
Cousins? Well, read the article from the first link. Need more? Would you believe that Derrick Williams is the better offensive player (better Ortg)? That he's equally as good a defender? That his career ws48 is better than DMC's? And...he's younger?
