Including 2010 the Big Sky is 16 - 18 in the playoffs. While most conferences save the Missouri Valley probably show similar records even the Big Sky's 16-18 is heavily tipped to one team, EWU. Take out the Eagles and the Big Sky is just 5-15 and other than EWU only Montana's vacated 2011 wins represent any consecutive playoff wins in the same season.
