The way I judge players is by a simple question "What NBA skill do they have?" Even Darko - on his worse day - can protect the rim for a 10-minute stretch. Kwame Brown is a pretty good post defender. Both are horrific busts considering where they were drafted, but both at least have a skill.
What is Vesely's skill? What is the one thing you know that he can do in the NBA for the next ten years?
