If I remember right, wasn't he a PG in HS, and that's what he was recruited as by Colorado? Westbrook was a SG in HS and college, and he was just an all-pro at PG. I'm not advocating that Burks is a PG or should play PG, but I don't see why anyone would be so adamant that he can't play PG.
Burks was 6'2" in High School too. He had a major growth spurt.
