I'm biased - as a Bay Area native, I will pretty much always believe The Big Game between Cal and Stanford is the best rivalry in the nation (you can talk when your team tramples a rival's band).
And as a Michigan alum, hatred of Ohio State and Michigan State is sent along with the acceptance letter. But I don't think I grasped the intensity of "Bedlam" across sports before meeting Oklahoma State University alum Jessica Lantz - it's serious, like life and death violently serious instead of "I had a higher high school GPA/I support public institutions of education you elitist prick" serious.
Anyway, the #17 Oklahoma Sooners and the OSU Cowgirls are engaging in a little women's basketball Bedlam on ESPN3.com at 8 pm EST. For Oklahoma, it's also senior night, with star point guard Danielle Robinson as well as Ben Roethlisberger's sister, Carlee, among the three honorees. I'll be watching just to make sure Jessica, who's in attendance, both represents and remains safe.
