I haven't compared UCF's football ticket prices to other non-Power 5 schools, so I admit I don't know for sure -- but it seems to me UCF is still a little high for this market, where there are several other things to do on any given weekend night.
For games like Temple, Tulsa and Tulane, I would price the lower-end tickets differently for at least one season and see how it went. For example, the Tulane game: upper bowl/end zone, the worst seats in the house, are $25 plus fees/service charges on Ticketmaster. So about $30/ticket, or $120 for a family of 4, to sit upper bowl end zone and watch UCF (coming off an 0-12 season) play lowly Tulane. Upper bowl/corner end zone on the home side jumps to $45 a seat plus fees/service charges, not even close to the 10-yard line. For a family of 4, that's about $200 to see 0-12 UCF play non-Power 5 bottom-feeder Tulane. And of course none of this includes food, drinks or parking.
You could keep sideline pricing the same, but open up 5,000+ "cheap seats" to make the games more affordable for alumni, fans or just families looking for something fun to do on the weekend. The reality of the Orlando market is that there is always weekend competition, but even if there wasn't, the product doesn't justify there being no inexpensive options for casual fans.
If you're reading this UCF, just try it for a season and see if you boost sales of the less desirable seats. I don't think it would hurt the value of the more expensive seats in the minds of the consumer, because you can still justify a premium for the good seats, and some visitor side lower bowl seats aren't much higher than your "cheap seats" anyway.
