I think it is useful when applied statistically. Large sample sizes can tease out temporal trends or correlations that may be hidden in more traditional statistics. I think this is true for hitting, pitching and defense. How does a guy's spin rate change after an injury or when he is fatigued? Is this guy's decline in offensive production due to bad luck or a decline in how hard or high he hits the ball? The speed, launch angle and location of a batted ball also help evaluate fielding. And I know that teams are asking questions much more creative than this. Of course there are flaws and I'm sure it can be over-analyzed, but I think any team that is not heavily using this kind of data is handicapping themselves.

Perhaps, but if your big stick Oscar is hitting 50 dingers annually for several years and then injures his wiener and his production drops to a 20/year level,
you know something is wrong. You analyze his launch angle before and after the injury and have an aha moment noting the reduction of his angle.
So then what. He's due up in the ninth facing a flamethrower. Does the manager then lean over to Mr. Mayer and say, "Oscar increase your launch angle", or does he hand him a new pitching wedge.
