I found an interesting little post at the Pro Football Reference Blog that asks the question:
"Which teams have played the best in each quarter this season?"
They take the Points scored in each Quarter, along with the Points Allowed in each Quarter to show which teams have the higest Margin per Quater (per Game). I updated the results through the Week 10 games:
1Q: -2.2 Margin per Game (#26)
2Q: +5.8 Margin per Game (#2)
3Q: -1.6 Margin per Game (#26)
4Q: +3.2 Margin per Game (#2)
That's right, we have the 2nd best Point Differential in the Second and Forth Quarters, but the 7th worst Point Differential in the First and Third Quarters.
