And the deck is stacked against any team in the upper midwest without access to an indoor BB stadium. So much of the season is played in "winter" in this part of the world. Baseball season starts 14 FEB. The Big 12 Tourney starts 21 MAY so by they time it is getting nice in Iowa the season is pretty much over.
Yes, there are successful teams in the Big 10, but historically pretty much all of the Big 10 faces the same issue so there isn't a huge disadvantage to just a few teams in the conference. It's not a coincidence that for the most part the national champions every year come from warm weather schools.
Did you know that in 1998 USC beat Arizona State for the championship by the football score of 21-14?
You don't have to got that far, but you have to have good indoor practice facilities, which honestly a lot of Iowa high schools and private club teams now have, where few did when ISU still had baseball. That still means totally front loaded, and probably overall heavily loaded road games, but nowadays there's so much more development that happens in indoor facilities, even in the south, that the weather disadvantage isn't so big.
Still, it's a big money loser almost everywhere. Now, if I got stupidly rich, I would happily dump a ton of money to build a nice little stadium, state of the art indoor facilities for ISU baseball, and NIL for players. But that's about what it would take for ISU to get baseball back.
