In reality, so much of this week’s game plan will be wrapped up in the idea that the Patriots get to an early lead. It’s always a point of emphasis for New England, but as was the case last Monday against Houston, you don’t want to dig yourself an early hole when facing the Niners, because they are very tough when they have a lead: on offense, that allows them to play to their strengths (running the ball and grinding the clock). And on defense, if they know a team needs to throw the ball to stay in the game, they can unleash Smith and a very good pass rush.
