Next year will be very exciting for the program and there should be at least an average of 25k per game. For a lark, here are my thoughts on attendance per home games next year, all contingent on good weather:

vs Old Dominion Sep 1 30k, standing room only
vs Norfolk State Sep 15 20k
vs North Texas Sep 22 20k
vs Troy Oct 13 22k
vs Idaho State Oct 20 20k
vs New Mexico State Nov 24 20k

Total: 132,000
Hopeful Average: 22,000
Unknown/Unforeseen factor average 19,000+

I originally thought the figures would be much higher, but the attendance for 2017 was significantly off from most expectations. More FBS team fans will travel. ODU will break and set a new all time attendance record, that should stand until 2019 when Syracuse comes to town. If 19+k fans average attend, a stadium of 25k will look nearly filled. Let's hope it's closer to 22k or greater.
