How was the competition that Jerry West played against in HS. Or, closer to home, how about Rick Carlisle from Lisbon, NY. He ended up playing a year of prep school which earned him a schollie to the Univ of Maine. You can google the rest of his story. Or even closer to home, and more relevant, Hal Cohen from Canton, NY.
But you are right. Class B players aren't supposed to be D1 players but there are rare exceptions. Girard was winning FT competition when he was in elementary school. He's a shooter. And the hoop is ten feet tall at all levels. Don't fault the kid from where he grew up and his hometown pride. Think of it as an asset and not a liability. It's bringing him to Syracuse. Not like these kids from Rochester who can't wait to leave upstate NY.
