Visualizing Drive-Point Efficiency - Week 1

Week 1 of the 2014 season is in the bag.  it's still early, and there will be a lot more regressing to the mean happening in the next few weeks as teams' statistical performance begin to more accurately reflect their true capabilities.

Last year I calculated the offensive and defensive DPE ratings using a normalized scale. This year I'm using the actual average points per drive.  It doesn't change the ratings in any noticeable way, and it makes the measure a bit easier to visualize.

I'm having some difficulty embedding the visualization, so until I can sort that out, you can play with the interactive version here.
