Fun with Numbers: Pass Defense

When judging pass defense, most of us just look at passing yards allowed or sacks.  I thought, why not rank all of those things and do some stupid number tricks to see a little more of the overall picture.

I present to you my Pass Defense Ratings:

The Method: Oakland only faced 470 pass attempts this season.  However, Pittsburgh faced 593 pass attempts.  To compare apples to apples I did the following:
1.    Sacks/Attempt
2.    Passes Defensed/Attempt
3.    Interceptions/Attempt
4.    TD Allowed/Attempt
5.    Completion Percentage

Sacks Per Attempt:  Oakland shocked me and won the "Sacks/Attempt" Category.  They got to the QB 10% of the time.  Baltimore finished last getting to the quarterback only 4.53% of the time.  The Jags finished 28th (5.14%).

Passes Defensed Per Attempt: Not as good as a pick, but if the defender bats the ball away it’s a positive outcome for the defense.  Philadelphia knocked the ball away 16.79% of the time.  Jacksonville finished dead last at 9.49%.

Interceptions Per Attempt: The best outcome you can hope for from a defender in pass defense.  Green Bay finished 1st, intercepting the ball 4.55% of the time.  New Orleans finished last at 2.63%.  Jacksonville put up their best finish at 20th (2.57%).

Touchdown Allowed Per Attempt: The worst outcome in pass defense.  Chicago finishes first, only allowing a TD 2.41% of the time.  Oakland, who led in Sacks/Attempt, finishes dead last after allowing TD Passes 6.17%.  Jacksonville finished 27th, allowing a TD Pass 5.53% of the time.

Completion Percentage:  Completing a pass isn’t the worst thing in the world, but I thought it would be good to weight this as well.  The Jets finished first by only allowing a 50.66% completion rate.  Indianapolis finished last by allowing 66.54% completion percentage.  Jacksonville didn’t fare much better at 29th (65.02%).

Overall: I took the average of the rankings to get a final score.  Ties were broken by TD/Att Rank since a TD is the worst thing that can happen to a pass defense.

The Flaws: There are a few flaws in this simple method. My main issue is weighting.  An interception should outweigh a pass defensed.  A TD allowed should outweigh a sack.  I just don’t know how much to weigh these things.

Final Verdict: Jacksonville’s entire pass defense is atrocious, finishing 31st.  They improved from 2009 at getting to the quarterback, but are still only getting there approximately 1 out of 20 pass attempts.  Not good at all.  Oakland is getting there 1 out of 10 times.
