Is being the youngest and smallest a bad thing? He’s pretty large, and skilled and fast for a 13 year old, but I can’t imagine that he wouldn’t be outmatched if he’s up against kids who are large, and skilled and fast for 17.
But he’s also a kid who doesn’t shy from challenge, so I think it could be a good challenge.
Is there a downside to him being outmatched? A chance that the coaches will remember that he was a little small and slow relatively, and not take into account that he was young?
