This has been a huge underdog series with the favorite being just 1-8-1 ATS during the past 10 meetings. 
I see that trend continuing here. 
Wyoming averages more points than Colorado State and the Rams defense has shown signs of slippage lately giving up 76 or more points in three of their last four games.
The Cowboys were impressive in their last two games defeating Nevada twice, winning by five and seven points.
