Wechson asked specifically about HA D1 communication. One well known Ivy RC has said that on Sept 1, he calls his top guys. How many? Supposedly over 20. My 2017 did not get a call. He got an email a few days later. That told us where he stood with that school. He already had his testing done though and it was clear he would be admissible without any problems. So they kept him around, but clearly he was just in case the top guys went elsewhere or could not get in...
If your RHP is low 80s, that will be where he needs to improve to get serious D1 (and even many HA D3) schools. The HA D1 schools do not really compromise on baseball players, which means a RHP for the most part needs to be high 80s/90. There are a LOT of RHP in the mid 80s. I am not saying your son cannot or will not get recruited by his dream schools, but that if the coaches have only seen low 80s so far, be careful about spending more money on their camps, until his velo has improved. Just my opinion.
