According to his birth record he will be 18 in late February. Don't know if he skipped a grade, started early, or took courses in the summer but this is unheard of today as most people are not allowed to start school after September 1st if they are 5 going on 6. My son was an October baby and we were strongly advised that he be held back and start school the next year. In no case I know of has anyone been allowed into school in the modern era if they are 5 on Jan. 1 of the school year.
I knew Pyton was youthful looking on the court but never thought he was just 17 and would not be 18 until 2012.
