Being #30 in passer rating, given the volume/ratio of passes our offense uses, is really damn good.
WSU is 3rd in the conference in yards per play:
Oregon - 7.32
WSU - 6.16
Arizona - 5.95
Cal - 6.14
UCLA - 6.21
ASU - 6.08
SC - 5.94
OSU - 5.67
UW - 5.36
Utah - 5.11
Colorado - 5.18
Stanford - 5.81
This tells us that while we don't have a "running game", our offense is one of the more efficient offenses in the country.
