It will be tougher for the University of Hawaii to get Pac-12 and Big Ten football opponents in the future after the two conferences begin a scheduling alliance, officials acknowledged.

The Pac-12 and Big Ten announced Wednesday a plan by which every Pac-12 team will schedule at least one nonconference game against a Big Ten member per season, beginning in 2017.

“That obviously takes a nonconference game off the table for those teams in the future,” said Jim Donovan, UH athletic director. “That makes it difficult since we were working from a limited window to begin with.”

The Pac-12 has in recent years limited its members from scheduling nonconference games in the first month of the season.

Pac-12 teams already play nine conference games. Add a Big Ten opponent and that will leave them with two other nonconference openings from 2017 on. In addition, some schools, such as USC and Notre Dame, have long-running traditional rivalries outside the conference, while others prefer to work in a Football Championship Subdivision “warm-up” game.

Teams that travel to Hawaii may play a 13th game but, increasingly, coaches have balked about giving up an open date or playing a conference game after traveling from Hawaii.

UH is well stocked with Pac-12 opponents through 2015, with USC (twice), Oregon State, Washington (twice) and Colorado (twice).

“The bottom line is that it is going to make it that much tougher for us to schedule those teams,” Donovan said.

In addition, the Pac-12 is also seeking to match its teams in other sports more often with Big Ten opponents.
