When I started the AC games in 1987, parents often requested to rank their player and with 300 scouts attending the games I could have obtain a summary on each player. Since I did not charge a player's fee I did not need the "problems" of making a decision that could effect a player's future. The Pro Scouts agreed.
The player know himself his rating. If he is a pitcher, the hitter will inform him. If he is a hitter the pitcher will rate his ability. "One on One", that is the game.
