Maybe it's been said, but if you do the reverse analysis (OSU's D versus PSU's O) I wonder what the result would be? I think the edge, then, goes to OSU's D. PSU has a pitiful offense, and hasn't faced that great of competition (as already illustrated). And it's still ranked low. However, our D is ranked fairly high - good competition or not. In the end, I think PSU's weak O-line gives way to our D-line and they don't score much.
It will still be something to keep an eye on - how well we can move the ball and score. I still remember dropping 63 on them last year. I highly doubt their D has improved that drasticly since then.
