Only want to add that I don't think Z-Bo is relevant to the search for late-inning plungers. His off-court stuff certainly played a role in his evaluation coming into the draft, but I think it's still pretty easy to find pre-draft evaluations. They say things like "NBA body, but lacking the athleticism to make him a franchise PF."
I think it's consistent to say a guy has a body that makes him a man among boys coming out of HS, and that fact makes him a major college prospect, but that the same body sends up red flags as being possibly too clunky to excel in the NBA. Like Tebow or Tommy Frazier can have skills that make them killer college prospects, but that any NFL team would have to be insane to draft one of them in the first round.
