We are not (and should not be) primarily a running team, but running improves our passing game by giving the D something else they need to account for. If we're not running enough to give them something to account for then our offense will struggle--see the first half of the Seattle game, where we were losing 7-0 at half time.

We had enough of a running game in the second half to outscore Seattle 12-0 (I still refuse to credit them with that last TD).

And that was with the same RBs we had in the first half.

That was the running game that Mike McCarthy abandoned without even seeing if we could run successfully against Seattle.

Just like at SF in the playoffs, we abandoned the run in the second half, scoring all of 3 pts before a mop-up TD in the last minute.

It's not a coincidence.
