Hoopscoop isn't the most reliable source, and I think they had him ranked high when he was in 6th grade through maybe 9th. I don't know this for certain, but I had heard that the Hoopscoop guy that rated players from Ohio and surrounding area was some relation to the Taylor's and that may have accounted for the high national ranking at the younger ages.
That being said, he's a great kid (as is his older brother) and is a very solid all-around player. He's got good quickness for HS, but I don't think his athleticism is B10 caliber, at least not for a team that is likely to contend for championships.
