Try to get to your State's PBR Top Prospect Game - in my experience this was a critical step in my son's recruitment as a rising senior/late bloomer - the event occurred prior to the summer ball season, was heavily recruited and provided tape and verifiable stats. That exposure, coupled with tape/stats allowed him to have meaningful communication in advance of key summer tournaments (wwba, etc) where they ultimately saw him play.
So PBR just sent him (upon request and some more info) an invite to their "Top Prospects (invite only)" event in May. PBR is fairly new to GA and took over the LakePointe facility from Perfect Game last year (I believe) so I'm not familiar with it and don't know whether college coaches will be there. Anyone have experience in GA with one? Regardless, the event does include laser timed 60s, video clips, etc. and is not too expensive so I assume there's no downside and he should do it.
