As of 8:30 PM PST/11:30 PM EST Boise State gives it's letter of resignation to the Mountain west

Source is from the Las Vegas Review Journal who reported that it was UNLV President Neal Smatresk who has broken the news.  You can find the link here.

The MountainWestHub twitter feed has confirmed it:

Interesting to note that there hasn't been any press release from Boise State themselves. Maybe they're waiting until 11:59:59 PM MST to announce it.  All we know for now is that the paperwork is in according to Smatresk.  Which now brings us to the next issue which directly relates to all things Big West: will BSU enter the Big West?

UPDATE: Brian Murphy from the Idaho Statesman is confirming this.

Have gotten confirmation that Boise state sent letter to all 10 mountain west presidents shortly before 10 pm mountain.

My guess is we won't know for another week or two.  Oh well, let the speculation continue...
