You probably know that WSU's basketball rivalry with Idaho is the longest running series west of the Mississippi (and the longest that doesn't involve the Ivy League), but did you know that the Cougs are also involved in another top 10 rivalry matchup on the hardwood?
Tonight, the Cougars will met the Oregon State Beaver for the 108th consecutive season. With their first meeting in 1909, the series is the 3rd oldest continuous game west of the Mississippi (and the 3rd longest that doesn't involve the Ivy League). Only Baylor vs. Texas stands in between the two long running Cougar rivalries.
