One thing I think people are forgetting about Darko, something that could be a real motivating factor... he was pretty much out of the NBA, no one wanted him and he had to take Vet. Min... he is only 27. That could have been the wake-up he needed... either he busts his butt or bust out the NBA! I think it was embarrassing for him. You can hear that from his media day interview... he was surprised that ANY team, let alone a contender, wanted him. I mean, he hasn't lived up to potential, his coach wanted him out (succeeded), and publicly questioned his work ethic (probably said worse to friends in the league behind closed doors (kinda like black-balled)... I'm sure that kept MANY teams away from him. When you take 1 mil to play on a team when you could get 6m somewhere else, that really tells me that you want this!
I'm not saying it will work out but think about those factors.
