We've heard the same type of stuff every year about how bad the Big Sky is....and even for a person like me who was all in favor of moving to the WAC it gets a little old.. We are a mid-major conference. Getting between a 12 and 16 seed is pretty much expected.
I know the Big Sky doesn't have a great RPI right now as a conference, but it's about where it's been the past several years, with an occasional good RPI year here and there, and we've faired pretty well in where our teams got seeded, especially if it's a team that's been in the tournament lately (PSU, Weber, Montana).
If either UNC, Weber, the Griz, or NAU win out (or close to it), it'll be very hard for them to justify a 16 seed for those teams if they win the tournament. If Weber or the Griz end up with 20+ wins and in the NCAA tournament, I wouldn't be surprised to see at least a 15 seed. If UNC struggles and just barely cracks 20 wins but wins the conference tournament, I could see them with a 16 seed possibly.
Take a look at the past 7 years, the RPI rating of the Big Sky team in the tournament, and the seeding.
2009-2010: #97 Montana (14 seed) - 22-9 overall 10-6 in conference.
2008-2009: #113 Portland State (13 seed) - 23-9 overall 11-5 in conference.
2007-2008: #83 Portland State (16 seed) - 23-9 overall 14-2 in conference.
2006-2007: #143 Weber State (15 seed) - 20-11 overall 11-5 in conference.
2005-2006: #61 Montana (12 seed) - 23-6 overall 10-4 in conference.
2004-2005: #130 Montana (16 seed) - 18-13 overall 9-5 in conference.
2003-2004: #126 Eastern Washington (15 seed) - 16-12 overall 11-3 in conference.

Either way, it's still too early for predictions to mean a whole hell of a lot

There's a lot of basketball left to be played.
