FORT COLLINS — The Rocky Mountain Showdown is obviously extending beyond the field, but Colorado athletic director Rick George isn’t sure the game will be played after 2020.

This, of course, was news to Colorado State interim athletic director John Morris, who noted there are still six games to be played on the current contract.

“CSU is ready to compete in this storied rivalry well beyond 2020, but it takes two teams to compete,” Morris said.

George told assembled media on Wednesday he has tried to have the series with Colorado State moved back to the campuses when the current agreement ends in 2020. Without naming names — but indications pointing toward Fort Collins — he said one party wasn’t interested in that move.

“After the current contract, playing the game in Denver is dead,” George said. “And I’m not sure where our series with CSU goes after that either. Today, we would not extend our agreement past 2020.”

Morris admitted Colorado State likes the game played in Denver, saying it gives a chance to showcase the Rams in front of a large alumni base in the metro area. In addition, he said it’s been a great experience for the student-athletes to play a game in front of a large crowd at a NFL venue.

George made his stand, saying he had the best interests of his school in mind, citing complaints from his season-ticket holders who feel they have worse seats in Denver than they are used to for home games.

Colorado has noted in the past it aims to have at least six home dates a year at Folsom Field, and with the Pac-12 playing nine conference games, some years that is difficult. Colorado State plays eight conference games in the Mountain West.

Morris, who wondered why this became a topic of debate on national signing day, said CSU is ready to bargain. Morris said the school would be open to other options, including switching sites every season, even from Boulder to Denver to Fort Collins. What he’s not interested in is playing two games in Boulder for every one in Fort Collins.

“No, we cannot agree to two games in Boulder and one in Fort Collins,” Morris said. “It would have to be a fair agreement.”

The series between the two teams is scheduled to be played at Sports Authority Field through 2019, then be played in Fort Collins in 2020, three years after Colorado State hopes to have its new on-campus stadium completed.

The two teams have met every year for the past 20, with 1993-94 being the last break. From 1952-82, a football game was not played between the two largest programs in the state.

Last year’s game in Denver drew 63,363 fans, the first time since 2010 the crowd reached that level. Historically, Colorado has sold more tickets to the game than Colorado State.
