I think this can be deceptive. Do we even get the 65 yard td pass without running the ball so much on first down? The safety bit on the run face to spring X for the TD. I think that has a lot to do with the large yardage when passing the ball on first down.
I'm going off of memory, but on that series we passed three straight downs and ended up getting a first down on a penalty. The next play was the touchdown. I would have bet $100 we were running the ball on first down based on how awful those 3 plays looked.
