I was going to respond earlier to your "frustrated" post... but decided not to, b/c it is frustrating... but it's hardly doom and gloom either.
It's not like we haven't seen this before... great defense, suspect/struggling offense. That could be said for much of the Tressel era. I'm "comfortable" in this area.
Perhaps the repeat NC expectations are unfair... but that is where the concern/criticism comes from. There are high expectations of this team. Not just from fans either. They aren't unrealistic expectations either. Outsiders expected Ohio State to be playoff caliber. The players and coaches set these goals for themselves as well. Even early in 2014, the line was that 2015 would be "our year". It happened early... and is/was amazing.
If this team drops a game, I think all the tension would go away. I found myself wondering during Indiana if it almost wouldn't be better for them to lose it and have that early "bad loss". The crazies going after Cardale on twitter would've been even nuttier... but at least it would've been out of the way then. Like Machiavelli said -- if you're gonna piss people off it's best to do it all at once in a massive violation than small little violations extended over a long period of time. I think that works on many levels... it'd almost be better to just drop a game and have that come-to-Jesus than continue "winning bad". Because these close games to inferior competition haven't served as the requisite wake-up call.
Something isn't "right" on offense... none of the players look like they're enjoying themselves at all. They look more likely to choke each other over a game of checkers than the opponent.
