Winning the conference in football is not that hard of a task comparatively.
I love how people think "anything can happen" in the conference title game as if the 03, 01 and 98 conference title games were some huge upsets. They really weren't each time the North had a REALLY good team, and people forget A&M was really good too. 1996 was a crazy upset.
In 2003, KSU was a 5 to 1 underdog to OU. I know because I was really into sports betting online at the time, and I bet $50 on KSU, thus winning $250. If only I had bet more.
But I get your point in that it should not have been that big of an upset considering KSU was a top 5 team in the preseason, and toward the end of the year in the games leading up to that was actually playing like a top 5 team.
