I'm a believer that standings don't mean the best coaching - especially at single 'A'. Based on how they conduct them selves on the bench, deal with players and referees, and teach the kids in the game, I would probably say the top three (in no order)....
This is only based on games my son's team has played against them. My son doesn't play on those three teams, but will probably try out for two of them next year. Hope that helps. Ignore most of the crap on here, some people have too much time.
