I don't know why people keep trying to bring this up, it really doesn't mean much. Pompey was a near unknown when we drafted him, I vividly remember the only "film" on him being a home video on Youtube of him shagging fly balls at some park (not a baseball field, a public park). The point? He was a blank slate and therefore his skills were a projection. To claim that Orimoloye is "miles ahead" doesn't all of a sudden mean that he's a much better prospect. Orimoloye has been on the elite circuit for ~2 years now playing with and against the top American kids in his class, he SHOULD be further ahead. That exposure also means that his flaws are a lot easier to pick out.
Had Pompey been in Orimoloye's shoes it is very possible that his skills would have been widely discovered earlier, and he'd have been a ~top 2 round pick.
