What happened: The Giants climbed atop the division despite losing their starting quarterback, sack leader, and leading tackler, per Ed Werder. Harbaugh took over a club that finished in last place prior to his arrival.

Why it matters: Before Harbaugh arrived, New York endured double-digit loss totals in eight of the past nine seasons. Sustaining contention despite absences at premium positions reshapes the NFC East race.

What to watch: New York will look to hold its division lead as the regular season continues with shorthanded depth on both sides of the ball.
