Well, on the probability scale, I like our chances at upsetting tOSU more than Purdue's chances of upsetting us. But I seriously doubt either one happens. Besides that, if we're actually having a good enough season to be in position to contend with tOSU, I would rather lose to them in the regular season if there is any likelihood of having to face them in the CCG. I'd hate to walk into that rematch having already beaten them.
Edit- I should clarify. I wouldn't hate beating tOSU regular season and that would be a huge, much needed boost for the program. So I'd sure welcome it. I just think it wouldn't bode well for a subsequent rematch.
