CBJ's last year at Cincy (actually 2011):
Rushing: 491 attempts for 2350
Passing: 392 attempts for 2699
That's a 56% rushing to 44% passing. It seems pretty balanced to me, especially since he won 10 games that year.
Like most coaches, he molds the offense to match the skill set of the players he has. Again, I believe, at least in part, they are calling plays they think Dobbs and company can execute well.
EDIT: The stats above are from 2011. Not his last year
2012:
Rushing: 543 attempts for 2695
Passing: 371 attempts for 3104
That's a 59% rushing to 41% passing
Yeah. I've looked at this myself. My response was to those blaming the OC while absolving CBJ. It is not realistic to believe DeBord in any way has free reign.
