Looks like 93% of capacity, though, which I believe was around 30th for P5 programs, and 4th in the Pac 12. The % increase (+18%) in attendance from 2015 was also 2nd in the P5 behind Miami, and top 5 in the country. Granted, most of the top 15-20 P5 programs don’t have much room for increase, but almost every Pac 12 program does and CU was far and away the tops in that category.
2017 saw a bump in attendance and increase to 94% capacity.
End of the day, I think there’s a compelling argument, based on one season of evidence, that the state of Colorado will support a winning college football program at a relatively high level.
