2020Dad, you might find this worthwhile: http://community.hsbaseballweb...r-at-certain-schools
All the velos listed were summer before senior year, or senior fall (unless the kid had a higher velocity from a prior time period, in which case i Used the higher velo). It's my only useful contribution to this community!
In my mind, in considering what is a viable option for my son, I discount the lowest one or two kids at any particular school, because who knows what special circumstances led to the kid being on the roster? Sort of, "aim for the middle of the fairway."
