Hall of Fame
I say any kid past age 12 with a 8 plus utr. Can deal with junk. That's a decent amount of kids.
It's more a matter of mental maturity. Can he resort to high percentage rally with low UE vs trying to hit winners on everything. He has the tools (slice, lob, loopy topspin). But can he put them to use because everything looks like an easy sitter to put away. For the most part, the latter is what you may be seeing.
