Depends on the level recruiting. They want the measurable AND the game play. I watched a lefty kid come in throwing 81-83 and completely shutdown a team of P5 commits and no one cared. There were probably 10 P5 coaches there and no one talked to him at all. You can throw a perfect game throwing 85-86... P5 coaches won’t even look. There are too many kids in that pool. They want it all, and if you only have 1...it better be velo (obviously just speaking for pitchers).
Pitching velo is really the only measurable that matters because it usually translates to outs. 90 off a tee means nothing if everything is a chopper. 92 across is infield is a waste if the footwork and hands aren't there.
Measurables are useful for projection. This kid is tall and skinny now - if we put some muscle on him this is what he can be doing. He only weighs 160 and he's already putting the ball the fence. Get him in a weigh room eating 3500 calories a day and watch him hit bombs for us. Kid has a cannon from short, wait until we work with his hands.
Colleges don't really want kids who are a finished product when they're 16/17. They want kids who are good, but they know they can get more out of.
