2013 - week 15 - GRIDs

QB Rating:

2013 - week 15 - GRID - QB rating

for clarity - 
NE 8.6, MIA 8.4
CIN 11, PIT 10
BAL -3.8, CLE -2.1
SD 7.1, KC 5.9



Team scoring efficiency:

2013 - week 15 - GRID - efficiency

The differences:
AFC North, PIT is ahead of BAL w/QB rating, but behind with scoring efficiency
AFC South, IND and TEN have flip flopped positions as well
NFC North, CHI is tops in their division w/QB rating and is 2nd w/scoring efficiency, DET is 2nd w/QB rating and is 3rd w/scoring efficiency, GB is 3rd w/QB rating and is 1st w/scoring efficiency.

So for the playoffs the NFC North is likely to be represented by CHI. I'm expecting a DET collapse and GB just doesn't have enough w/o QB Rogers.

IND who has backdoored (did not win their game) their way into their division championship this past weekend will be the easiest of home field opponents for either MIA, BAL or KC.

BAL is in the drivers seat for #6 seed in the AFC, but MIA has been playing well these past three games and winning in the cold (sub freezing and snow) at PIT last weekend, really puts them on my radar. BAL was a bit lucky last weekend vs MIN, maybe their luck holds thru DEC, if not MIA is in.

FYI:
Again these are cumulative totals for the season and are derived from the O performance subtracted from the D performance to arrive at a number that seems to represent the strength of the team.

For QB rating, I take each games QB rating and subtract one from the other to arrive at a number. If two or more QBs played during the game I take their total number. You'll find the QB ratings in the GameBook.pdf file available for download after each game at nfl.com

For Team Scoring Efficiency, I take each drive/possession and it's outcome and divide the scoring drives from the total number of possessions. I do take into account punt returns and kick returns for TD as scoring drives/possessions. From my point of view each possession by a team is an opportunity to score.
I then take O possession/performance and subtract from D possession/performance to arrive at a number that seems to indicate the strength of that team. The higher the positive percentage the better the team is at scoring and winning games.

Perhaps later on I may institute a more recent indicator covering the past 4 weeks, rather than just a season long cumulative total which can be deceptive while reviewing a teams recent performance.
