I've hated the current format for years, so almost anything that doesn't have a meaningless seeding game would be an improvement. Likewise to portions of the post season being single elimination, portions double elimination along with the Wednesday game that doesn't accomplish anything but provide rest for the #1 pitcher.
1. It starts with allowing the districts to determine their own post season format including automatic bids for regular season champs. There needs to be a uniform district tournament format that everyone must follow.
2. Once the region participants are decided, I like the double elimination region or substate tournament. It is an early indicator of what is needed at the state level rather than riding one arm. Single elimination games promote arm injuries. The pitch count/days rest only marginally help.
3. Another idea is a super regional where 2 regions are combined for one big tournament and the winner goes to state. It's an 8 team double elimination tournament just like the state tournament. A one horse show will not be able to survive. Best pitching staff should win and the lopsided games are at this level rather than at state. Hey T$$AA! More $$$!
