There's a guy who went to my college, Jared Jordan- Fairly nondescript athlete, 6'2 slow white guy. Basketball is basically his life, worked his ass off more than anyone and studied the game to the point where he knows it more than the coaches do. He was drafted in the 2nd round of the NBA draft a few years ago, never made any teams' roster. All the scouts said the same thing- absolutely no upside. Now he's playing in Europe. That is about the ceiling of what you can do without being 'gifted'.
