The stat cast average ev is irrelevant because peaches grandson isn't facing 90mph sliders. 15u pitching has far less variables, and thus the average exit velo will be much closer to max. No matter what stat cast measurement your sort by, there is almost no correlation with top players. Guys who hit 35 home runs have ev 10 points lower than AAAA players. You might not have read my post; I refer to stat cast data several times. I simply deduced ev off a tee by subtracting the help of the pitch from the max reading on stat cast. You also make a key miscalculation in saying the average ev is 20 mph below their max. The ball is going to add 13ish ev, so a 110 on stat cast is a 97 on a tee, meaning an average of 90 is only 7 mph, not 20+ below their best. If exit velo from a tee didn't matter to someone, then no one would measure it. It's like the vertical jump in football, raw power output.
