My son "played down" to a national championship D3 that went to four straight league championships, NCAA regionals, and one CWS while he was there. I have said this for a while.... It is a hell of a lot more fun playing for a winning team than a mediocre one regardless of level. Also championship games; whether league, NCAA regionals, or CWS at any level are SO much more fun and exciting.
Winning puts a spring in your step and makes the trip to the hotel bar after the game so much more fun!
As always JMO.
