Are the community spectators the ones on the overpass?
I really do not think this is about SU. This is about the amount of road games. It's about money (they have a nice season ticket base). It's also the fact Maineri does not want his kids missing class. This is the SEC where you leave town on Thursday for a Friday series because of travel. It's not exactly a bus league (though some trips are for some). If you are out of town midweek a lot, it is rough. Having less than 30 home games would not be acceptable for LSU. Not acceptable for many in this region. Heck, UNO is home first three weekends OOC - first four total if you include conference opener.
Payouts for baseball are extremely low. I was shocked when I learned some of the figures. At least for a crosstown game, you may be able to pocket some, if LSU is willing to pay SU as they would out of town teams (doubtful).
