I lived my whole life in PA, so I didn't hate them at full Jax levels initially. I can remember seeing a Michigan jersey at a Wendy's one night after they beat Penn St and giving him a nod, and he gave me one back. I don't see myself ever doing that again. Ever.
I remember rooting for *ichigan in 2005 to beat Penn State. But that was strictly for Ohio State's gain - not an anti-Penn State or pro-*ichigan reason.
I remember rooting for *ichigan in bowl games, because I felt a win for them was good for the Big Ten and, therefore, good for Ohio State.
But that's changed. Eff them in bowl games. If Ohio State needs a *ichigan win, then..... meh - MAYBE I'll root for them. But I still find MSU's win when *ichigan's punter dropped the snap hilarious. And that game was what kept Ohio State out of the Big Ten championship game that year. Well, that, and Ohio State also lost to MSU.
