"I think it starts months, years in advance," UC Davis Athletic Director Rocko DeLuca said. "The formula is pretty simple but this year presented some big challenges to figure out how we were going to message and get things done in a safe way. I think on the heels of the pandemic, people were so excited to get together and celebrate something like a football game and that helped feed into it. But you look around the area and that wasn't the case everywhere so I think it was a lot of hard work by our external staff to message and communicate some of those pieces."
“ Despite not being able to host large scale events for a full year and not allowing more than 10,000 fans in the gates until the second home game on Oct. 2, UC Davis' entire season attendance net 11,000 more fans than 2019. The Causeway Classic on Nov. 20 saw a stadium record for attendance and average attendance over five home games surpassed 10,000 spectators.
All of that turnout translated to a 29 percent increase in revenue over the 2019 season, including two record-setting single game revenue marks in homecoming on Oct. 16 and the Causeway Classic.”
