lol...Including, but not limited to:
Rate the Umpire
Rate the Announcer
Rate the Concession Stand
Rate the Bathroom (this might be the most important)
Rate the Rater
Rate the Ump Behind the Plate
Rate the Base Ump

If I'm not mistaken, in public education the coach is rated by his administrator/athletic director. Much as in private industry, the boss rates his worker(s). I guess if you want to rate the coach you can become an administrator or AD.
