Honestly, if you throwing mid 80s at 14 years old he will get a write up at the showcase, even if he doesn’t land a strike. Does it mean anything? not yet. It’s a good experience and it helps them become more relaxed when they are put on the spot to perform. They will usually note projection but 6’2 at 14 isn’t small. My son grew later and we viewed it as a positive. If he could hang when he was smaller, he would be just fine when he grew.
