Here some of the specifics of Boise State's decision
Navy, once considered a lock for the Big East in expansion, now says it cannot join the league before 2014.
Air Force, long considered a target for Big East expansion, will remain in the Mountain West, forcing the Big East to find at least one additional football playing member.
The Big East officially welcomed five new members to the conference. Here's a quick look at the five new members.
The Big East will reportedly add Boise State, San Diego State, Houston, Central Florida and SMU on Wednesday. Air Force and Navy are expected to join later, but Temple could be a target if Air Force doesn't join.
After two months of waiting, the Big East appears finally ready to execute a plan to expand the conference to 12 teams by adding San Diego State, Houston, Boise State, SMU, UCF, Navy, and Air Force.
The Big East continues to work to expand to 12 teams and one report indicates one target, Air Force, isn't going to decide any time soon.
After once appearing promising, the BYU to the Big East negotiations have broken down and it appears an agreement will be reached to allow the Cougars to join the league as a football only member.
