Can anyone speak for D3 schools? Colleges come from everywhere at HF, Showball type of events and can only see the kids a couple of days, or couple of showcases. Is that enough?
Depends on the kid in question. To quote one D3 HC about Headfirst, "There's 10-15% that everyone wants...the trick is to find that other 10% that are just as good of a fit for your program, but aren't in the top group."
My kid went to Showball and HF, one after the other. Showball didn't work for him, at all(others have the opposite experience).
HF allowed him to show his stuff to schools who had only seen him on tape, show off his stuff again to schools who had seen him, and introduce himself to new schools. He got a lot of interest from high academic D3's, and from D3 schools in general. Probably a little but late in the day(August) as a non pitcher to get D1 interest, but he had some camp invites from a few D1's, also.
In the next three weeks he had probably 8-10 legit contacts/invites to camps from schools who were there, and some other contacts from schools who weren't there? Some simply weren't a fit for him, but a couple of others were from schools that he had never approached. He only went to one camp, and visited about three schools after HF. all but one offered him a spot...the other wanted him to show up at their fall camp, but he simply couldn't fit them in. Since he already had a couple of firm offers from some excellent local D3 schools that he really liked, he could afford to be picky, and he was.
I would say that he was in one of the top two groups in my first paragraph. Ran a sub 7.0 60yd, throws in the 90's from the OF, has a very good, versatile glove, and hit well-no bombs, just line drives. ACT in the 30's, good GPA.
His negative, was his size...5'9".
I think it's really hard to generalize about how successful your player might be until you are more specific about him, and realistic as to how he showed. Some schools are crying out for players(i.e. Engineering schools, schools with lesser reputations), others can pick and choose. The service academies are very approachable, but getting accepted into their schools is not easy.
