Do I think he'll lead the Wolves to the promised land? Nope. But it does show the sad state of affairs when there's such a value on players who actually bother to play defense, aren't lazy, and aren't prone to ridiculous mental lapses. You could argue the Cavs are doomed to keep falling short to the Warriors because of their lack of two-way players, and I think lots of front offices are seeing that issue now...despite the run and gun, 3-happy league, it's still important to get stops.
