I'm torn. I root for 2 teams - ISU and who ever is playing Iowa. My youngest has even been giving me a hard time about "who ever is playing Iowa" - "Dad, that's not a team!" As time goes on, I think I'm becoming more indifferent to TOE. Who cares if they win against a mostly garbage slate, and get hammered by the few teams they play that actually have a pulse?
But in my universe, tOSU has done more to harm ISU. I blame Woody Hayes for ruining ISU football when he punched that kid and they hired Earl Bruce away. Further salt in the wound was hiring Dirty 30 team member, John Cooper (I know he was still salty about ISU's admin blocking his hire way back when, because he didn't have HC experience or some such nonsense...) Almost like Auburn more recently has been into getting the best from ISU (Chiz then Leath), tOSU was once big on getting ISU's best. Even more recently getting Herman as OC. I can't stand the Buckeyes.
So I'm rooting for tOSU to lose by 1. 3-2, Hawks.
Other odd Cooper rumor I remember: spring of 1999 or 2000, rumor was going around campus that Mac was going to be let go because Cooper wanted to revive ISU. Doubt there was much weight to it, but yeah. It's like when my mom called the Chiz hire after half of '06 KU game, before Mac even resigned, "I just talked to someone on the concourse that says we're hiring the defense guy from Texas." Mom didn't follow FB closely, went to games to spend time with family, must have actually talked to someone with connections...
