The best drive (roughly 8 min., resulting in a TD) was in the 3Q. Nine of the 12 plays were running plays. It effectively put the game away.
I assume you mean the next to last TD drive, which started after the Ravens scored their TD. They started at their own 20, and by three runs and four passes (including the 35 yarder to Walters) got to the Baltimore 19. They eventually punched it in by running three times after first and goal.
That was a nice drive, which they needed after Kubiak gift wrapped the Ravens' score the previous drive. But the impressive one was the last TD drive, where they ran every single play.
Again, my gripe with Kubiak was having the big lead in the 2nd half, and starting the half with 6 out the first 10 plays being a pass. Thankfully, he wised up and pounded the ball after that.
