HS coaches: When/Why drop someone sidearm?

I threw mid 80’s in high school from a high 3/4 arm angle. Got to JUCO and dropped mostly sidearm/low 3/4 to get movement and was still 84-85. Have you ever dropped a kid sidearm in HS? What are the things you look at in determining he will not be able to be successful over the top?

As a HS and college coach, I’ve never dropped anyone down from 3/4 to sidearm, but it happened a lot in pro ball for guys that couldn’t make it throwing over the top. Ultimately, they didn’t make it to the big leagues throwing sidearm either – but it did prolong their time in the minors.

What are you seeing in your area Brett?
