I watched Manute play quite a bit while living in DC. Was never much of an impact player because he was a rail and had little offensive skills. His son is 5" shorter and already weighs in 20 pounds more than dad. And it sounds like the kid can shoot.
He will be interesting to follow, no doubt. But I imagine that a 7-2 kid on a HS court has a bit more advantage than he will at the college level.
