Hall of Fame
He could have played up all he wanted in the section as you suggest and it still wouldn't get him in a L3 national this year. The current national selection system is stacked against first year players irrespective of abilities. For those who planned and probably a little lucky like my kid, it proved possible but tough to succeed as JM suggested because of the gap in age.
If the goal is to get the "best of the best in your age group" as you are advocating then the USTA should do away with allowing a quota of the younger age group at each tournament. And if a former #1 top 20 national can't get in then I think the rest of us are in big trouble.
I agree that the first year is tough but playing up within his section will make him a better player. Personally, I don't get caught up in rankings or L2, L3, etc... particularly in the younger age groups.
