The points are a bonus as I believe McNeese is the superior team. Certainly the Cowboys have the better overall record being 7-9 while Lamar is 3-11. 
There is no doubt who has the better offense. It's not Lamar. The Cardinals average 63.6 points per game, which ranks 320th. McNeese State is the eighth-highest scoring team in the nation at 84.9 points a game. Lamar surrenders 76.9 points per contest. 
The Cardinals are 0-10 when they permit 66 or more points. McNeese State should have no trouble exceeding that number.
