When this controversy began brewing yesterday I felt the same way, and I am not a fan of championships with asterisks. Certainly OSU can make the case that their situation is no fault of their own. I don't blame OSU at all for feeling like they have a case to be made.
But if you want to play the "woulda, coulda, shoulda" game at some point down the road, don't create a rule to begin with. Plan ahead and create loopholes, contingencies, or caveats - but don't put it on paper if you think there is any possibility you might change your mind. Because then you screw somebody (or everybody) else.
Yes, OSU would likely be 7-0 at this point. But they might be 5-2. They might have had key players injured in those cancelled games prior to playing IU and lost to IU. They might have had their own Covid outbreak and been unable to play us had they played those games. The "might haves" are infinite.
So if you committed yourself to a rule at the outset, honor the f@#king rule. Otherwise you have no honor. And nothing is worse in sports than being dishonorable. Especially true for an organization like the Big Ten that claims to have such lofty ideals.
