I disagree – 1D% is a better measure of offensive play than C%, but as long as the offense is getting first downs, it doesn’t matter if they come through passing, or running.

Moving the ball forwards is always better than not. Therefore, completion percentage (as long as we’re assuming not a lot of backwards passes) is a good measure. Whether a given play which attains forward movement gains a first down is subject to a lot more than the passer – there are random elements, and more significantly playcalling aspects to consider.
