I had to look up my sons PG profile for the height and weight. He has an August bday so he's always the youngest in his class.
Rising 9th grader (12u) = 5'7 and 145#'s
Middle of 11th grade = 6'3 and 210#'s
I swear last year he went to bed with a stomach flu for 2 days and woke up 2 inches taller! I'm expecting around 6'4 by the end of his senior year.
