In googling Shaun Manning, I can't quite make out if he's a really good guy, or perhaps a pretty bad one.
On the one hand, he claims to mentor kids, in basketball and in life. He teaches them fundamentals of the game, and he also provides a home for many of them. On the other hand, there have been others, like him, who use their contact with budding stars, to cash in. There are rumors of him "selling" players to schools or agents. As a parent, I'd have some concerns about handing my kid over to a man who's known as "Ice".
He played an early role in the development of, what turned out to be the rather sad story of Jeremy Tyler. A San Diego phenom, who skipped his senior year of high school to go to Israel and play there, in preparation to becoming a top pick in the 2011 NBA draft. It's all gone badly for him, and he's currently playing in China. You can read a NY Times piece about Jeremy from 2009 by clicking the link.
One hopes that Manning's motives are pure, and he influences this particular kid to become a Runnin' Rebel. If he does, he will definitely receive good instruction from Marvin Menzies.
