Exactly. When I was still working on that side of things, all coaches would receive weekly reports of prospects in their area by school. Each coach would then have a binder that contained a sheet with all that school's information (some of the information was extremely granular i.e. secretaries who had a son who went to our school, etc..) including a list of all prospects. If Rob didn't have something like this available to him when he went to Don Bosco Prep (we aren't talking Weedsport or Parsippany here) then the recruiting infrastructure is even worse than I could ever imagine.
For the record, I'd say it was a 60-40 split on where the information came from between the coaches actually on the road recruiting or the on-campus recruiting staff. That is why these people are so valuable.
