You are correct that usually the increase in attendance doesn't relate to straight equivelents because normally that increase is going to come in the form of lower priced tickets but it is still a significant amount of money in. Those added tickets, even at lower prices also translate to increased concession sales, parking etc. and value for in arena promotion. Add to that that a good number of those higher priced tickets are being purchased by people who started out sitting higher up. You have to get them in the arena then sell them up.Bohn 100% got hoops, invested in the students, and got CEC to fill pretty well. It helped that we were dog-butt bad at football, but he was all in and did great things. Even into the early RG years, attendance was good. If you are bored, still using X and care to look, you can find old posts from when Rick started the Allbuffs account, calling out early RG's lack of support for hoops.
Here is old data from TRR - you can see the trend under Rick. Other factors driving attendance both up and down have been the quality of the team and schedule, as well as how good the team was the year before. It's roughly stabilized around 7k +/- 1k depending on factors mentioned above. It also really hurts us that, because of the huge home court advantage we have historically had, no one of note wants to come for the non-con.
2015-16: 62,966 (7,871). (Partial)
2014-15: 66,468 (9,495)
2013-14: 84,133 (9,348)
2012-13: 61,513 (10,252)
Also, tickets have gotten really funking expensive under RG - what used to cost me $1200 for two seats and primo parking (comped because of football spending) would now cost $1900+ 5k donation for the parking.
Cal-Baptist this year was the first time in 14 years we had drawn under 5k for a game.
"Average home attendance as reported by the NCAA is 7,013 per game over 18 home games. Up that attendance by say 1500 per game and you have increased your revenues by the equivelent of about 2 additional games, without any of the associated cost."
Although it seems logical, it doesn't quite work this way because the increased attendance comes from cheaper tickets; the nicer, more expensive seats are locked up in the season tickets.
This is the same thing with increasing the numbers of students. You have empty seats, turn them in potential future revenue (and more students increases the energy in the building making it more fun for paying fans.)
