If your one of the top recruits in the nation in a given year, why wouldn't you go play in a conference where you play high major talent all the time, gain greater exposure, and have your chance to prove your game night-in, night-out, against guys who will actually end up playing in the NBA? Sledge makes some sense, given that he went to a team in a big conference and didn't get PT as a freshman (and is from the area), but Turner was ranked as one of the top guards overall in his class.
