Despite the Big East wanting Navy to join the league before its scheduled 2015 arrival, athletic director Chet Gladchuk said Navy will not join early.
"There's a laundry list of reasons why we can't join in 2013 or 2014, and none of those objectives have changed," Gladchuk told ESPN. "That's why we determined 2015."
In January, Navy and the Big East announced Navy would join the Big East in 2015 as a football-only member. However, new Big East commissioner Mike Aresco said Saturday he wanted to talk to Navy about coming on board before then.
"What makes sense for us remains 2015," Gladchuk said. "As it stands today we're still focused on (joining in) 2015."
Navy can't join earlier because it has games scheduled through 2018, bowl contracts through 2017 and television contracts with CBS College Sports -- and CBS Sports for the Army-Navy game -- through 2018, Gladchuk said.
Navy also is scheduled to expand its home stadium by 3,000-4,000 seats by the 2015 season and has other facility on-campus "fine-tuning" improvements to coincide with its first season in the Big East, Gladchuk said.
Next season, the Big East loses Syracuse and Pittsburgh to the ACC but will add full members Houston, UCF, SMU and Memphis and football-only members Boise State and San Diego State, giving the Big East a 12-member football league.
Aresco has said the league wants to add another member besides Navy to become a 14-team football league.
Last month, ESPN reported the Big East is split on pursuing BYU or Air Force as the 14th football member and also would consider going to 16 schools if it could add BYU, Air Force and Army.
