Average exit velocity is one of my favorite stats. No doubt over a long period, say 100 at bats, it means a lot.
That said, outside of MLB no one is capable of compiling average exit velocity. Only place we can do it all the time is in our indoor leagues using HitTrax.
Also if we see any player that has an average exit velocity of 96, that player would be a first pick of the draft possibility. Because there is no player that ever lived that would have an average exit velocity that high. Surely we must be talking about "peak" exit velocity 96.
Exit velocity off a Tee shows strength and bat speed. It doesn't tell if someone can hit. It's exit velocity in games that count.
