Just as likely that the opposite is true. The better you do on defense, the better the offense performs. Better starting field position for the offense results in a more open playbook and better scoring chances.
Now if you said OSU, that would be a good example.
That said, we have been offensively challenged for many, many years pulling up the rear in conference in points scored.
Yardage gained/allowed is integrally/indirectly linked to the number of points scored.

Looking at yardage impacting wins or losses (70 yards out averaged a game):
2003 was a bad year.
2013 was awful bad too.
2012 and 2010 were not so hot.
Looking at point differential (greater than 10 points differential):
2003 was horrible.
2006, 2007, 2008,
2013 were not so good for POINT DIFFERENTIAL.
As far as wins go, 2000 was the year with 9 wins, the only recent great win season.
