disclaimer here, my son is not a pitcher, and I know nothing about pitching. One thing I have noticed in the last three years of watching kids he has played with is velo wasn't the whole story. He plays with a RHP, 6-2, 190 that sits 86-88- I've seen the college recruiters guns. Kid has had some interest, but not one offer. This is a mystery to me. Kid is a good athlete, two way player and swings the bat pretty good. I do know that he was telling the other kids that it was D-1 or nothing- so I'm guessing he would have had an opportunity to play somewhere.
Had another RHP that graduated last year- was 84-86, ended up going to a good D-3, he was 5-9, 155-160. I have to believe in this case he just didn't project well. he did end up being the number 1 starter for the d-3 he went to as a freshman, so it worked out well for him so far.
