Ryan Richards is a 19 year old kid from Canterbury in England. Unheard of I'm guessing for most people in the US but I played with the kid 2 years ago a few times (I crossed him up actually, but that's a story for when he's drafted, ha!) and spoke with him. He seemed humble and focussed.
I don't know how good he will be, and I can't say with any certainty that he'll definitely be drafted -- he's being closely monitored by the Bulls and the Pistons -- but it's certainly interesting, for me at least, that a guy I played with, whose brother I'm friends with, could be in the NBA.
