OF04, I don't know what PG has ever done to you personally that you harbor such a resentment towards them. But, never mind that.
I believe that if a player never attended a PG Showcase it would be difficult for PG to have a profile on that player. That would make sense. However, I don't think that the absense of a PG profile would keep a player off of a Baseball America player ranking. Whether it be PG, Team One, Blue-Grey or others, they know who the players are and I don't believe that any one of those organizations would intentionally penalize a player because he didn't attend THEIR event. JMO.
