Strangely, this kid reminds me a lot of a 7 foot player whose name was Lake, I believe. He played for the now defunct Laurel Crest Academy in Bristol back in the late 1960's. You almost never saw 7 footers playing BB back in those days at the HS level. This kid was a legit 7 feet, and probably a ringer because he appeared as mysteriously as he departed. I think he may have only played for one or maybe two seasons at most. He was their version of Nadav Henefeld.
He was a fairly decent player, nothing special, but had pretty good fundamentals. He was slower than molasses, but hey, a 7 foot kid on a HS BB team in the late 60's meant nobody could guard him.
During his senior year, Laurel Crest did something they had never done in their history. They scheduled the local Bristol high schools, and I'm pretty sure they beat Eastern, Central and St. Paul's with the big guy. The games were fairly competitive, as I recall, but they won 'em all. They finally had their lone season in the sun vs. the townies.
Laurel Crest went belly up a few years later.
