Why would a contender part with a first for a non-shooting "energy" guy whose defense is extremely suspect? I'm sure Vando is a great dude, but that player type can easily be picked up off the trash heap.
You don't win in the playoffs with energy guys with no ball skills. The game slows down in the half court, matchups are analyzed under a microscope and all flaws are mercilessly exploited. Vando has SF size but can't stay with anyone on the perimeter or shoot. That's.... not ideal.
Vando often looked decent on the Wolves when he had four scorers around him, but they won despite him, not because of him.
