  • Take the over (5 units) 

The two teams play at a slow pace with Washington State ranked as the 203rd fastest team in the nation. Oregon State plays even slower as they are the 322nd ranked pace in the nation. A slow paced game will not cause a low score game as both teams’ defenses are really poor.

Expect a high scoring game between these two teams desperate for a win. The over is 4-3 when Washington State has played at home, too.
