The Big Sky Conference and defense are words that don't go together. The Over often is the way to look in Big Sky games and this matchup is no exception. 
Both teams are playing better and more offensive-minded rather than defensive-minded. Idaho State is averaging 84.2 points in its last four games. 
Northern Arizona has a decent scoring backcourt with Cameron Shelton, one of the better players in the Big Sky, and Luke Advadalovic averaging a combined 32 points per game. The Lumberjacks are averaging 81.5 points in their last two games. 
The combined total in two regular season meetings between these teams last season was 149 points.
