We have the better offense while they have the better defense. I'm thinking it'll be close but there's no overwhelming reason to see why we shouldn't have a competitive advantage, so long as we execute decently. I seriously doubt that we'll fail to, at least, be highly competitive.
Be aware that Dak has performed better than he should rightfully be expected to in every game he's played thus far. There's no reason why this team shouldn't continue on a winning path vs. San Francisco, barring an overly sloppy game on our part.
Nevertheless, with pro football being as competitively demanding as it is and allowing that we'll be at their place, anything might well happen. No doubt, we'll be challenged but there's no just cause to believe we should be at a disadvantage, despite playing on their field. I'm very seriously anticipating the Cowboys enjoying a hard fought win in San Francisco on Sunday. Maybe we should all feel likewise.
