CBS Sports adds up the BCS finishes by conference from the past five years based on 2014 conference memberships and “Iowa State is the only [Big 12] member without a Top 25 BCS finish since 2007.” However, that status is due to Texas A&M storming off in a huff going to the SEC. Kansas may be back to doormat status, but at least they have 2007.
To add insult to injury, the auto-formatted link in that sentence on the original page is tagged for the Iowa Hawkeyes. (Oregon State’s link works.)
