As far as the HF pitcher velo opinions on this thread, I'd say everyone is correct.
Yeah, lots of kids 76-79, most 80-84, some 85-87. I've never seen 88 at the two HF events son has been to, and I too am a "Stalker stalker," annoyingly peering over the shoulder of the college coaches with guns.
The wide range of velos however does match the wide net that HF does a great job of casting for both skill levels in prospects and NCAA division levels of the schools they draw to their events. Look at the list of coaches attending a HF event. You've got many small Division IIIs all the way through top D-1s. So with the wide range of schools there, HF must also have a wide range of arms for all types of schools. And that they do. And I think they do it well, the mixing of 78mph arms, with 87mph arms, for a well run recruiting event for all parties involved.
