Check your WBB numbers. There are huge TV dollars out there for the P5 schools. Don't confuse "revenue making" with "nobody goes to the games." Allocated funds from the NCAA and SEC for WBB are big...even though it has a tiny fraction of the fan base that football, MBB, baseball, and even softball have.
If baseball adds more seats for the purpose of increasing revenue, those added seats will have to come in the form of suites, premium priced areas, and reserved seats. In other words, if baseball wants to make money off of added capacity, it won't be because the amount of student/GA seats are increased.
Television contracts drive everything, which is why FB, MBB, and WBB are financially strong. Baseball and softball are getting better, but they still do not have the national TV exposure the other sports have.
But those who hope in the LORD will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint. Isaiah 40:31 (NIV)
