The weather aspect alone is a great thing imo. This tournament is enough of a stress on players as it is but throw in a couple extended rain delays and it becomes almost not worth it for anyone who doesn't need the auto bid to make the field of 64.
Yeah If you want to win through the losers bracket (which i dont remember anyone ever doing since we've been in the conference) you end up having to play 6 games in 5 days, nearly impossible for a college staff that's been playing max of 4 games a week all season.
I'd say the biggest hindrance to attendance is the format, it doesn't makes sense from a fan perspective especially if you want to come from out of town. Currently you are only guaranteed to play Wed/Thursday, and by Friday there are only 2 games. So at least half the fan bases are eliminated before the prime game times kick off for the weekend.
And then Saturday there can be up to 4 games depending on outcomes, however most loser bracket teams are out of pitchers and there are generally just 2 games starting at 9am in the morning, also not ideal. On top of this there are the weather/extra inning delays during the first couple days, which just pushes everything back throughout the day. I used to work in downtown OKC and could just walk over whenever the Frogs would start. However even planning that was annoying when a 12:30 scheduled 1st pitch would get moved to 2pm and you have a wasted afternoon at work waiting for other games to end.
Not sure on the rules on this, but I've thought they should have just gone to an 8 team, single elimination tournament starting on Friday to make it a 3 day weekend for the whole conference. A full slate of 4 win or go home games on Friday would be a fun all day event for the college baseball fanatics, 2 game semifinals on saturday could kick off early afternoon, and then the finals on sunday afternoon. Would be a lot easier planning a full 3 day weekend as a fan than the current setup, where you are guaranteed to only play on in the middle of the week. Plus you'd be seeing the best pitchers all weekend, not middle relievers starting semifinal games like we have currently.
