PG has proven to be a fantastic company and done a great job putting a lot of baseball recruiting content together like never before. If there is a curse (besides coaching staffs being lazy recruiting and just hanging out at PG events all summer) is that it prices out a lot of talent. There are a handful of solid ball players completely alienated from the recruiting process due to the outrageous money ball tactics of showcase baseball in general, not just PG. It's sad really. Guy A with average talent and money will easily have more options than Guy B with above average talent and less - no money for example.
My son is an example of one of those where we just could not afford to send him to a PG type showcase.
Through the work of his HS coach he was recruited by a D2 JuCo. From there he was noticed by a D2 university which ultimately offered a nice scholarship.
There are alternatives, but PG and similar outfits definitely makes it "easier" for a ball player to possibly get noticed. Unfortunately, putting on such events cost $$ - that's just the way of the world, like it or not.
