Just spoke to HA D3 son.... best D3 teams had several guys sitting 88-90, with maybe one guy sitting 90-92 (top pitcher at Tufts with Cape invite and two pitchers at Eastern Conn). The majority of bull pen would have guys 81-85, with the exceptional nasty slider guy throwing 76-80 as the closer.
A number of the better pitchers had low to mid D1 offers but these kids were searching for higher academic where they could get on the field quickly. Most are late bloomers from both a size and/or development perspective.
Haven't even mentioned how many D3 hitters can face top D1 velo and command. Not many; a few here or there.... Son's buddy was at a top performing HA D3, he was drafted junior year, and he is one of the top hitters on his low A team and league. Rare feat. We won't be surprised to see him in double A this season....
