I don't agree on this one. I don't like to talk about stats because they only tend to give a partial picture of a situation, but in this case they're necessary. -There's a strict correlation between teams who entered the playoffs and their run-D ranking (8 of 12 teams rank in the top10): #1 SEA, #3 DEN, #4 CAR, #5 PIT, #6 ARI, #7 CIN, #8 KC, #10 HOU. The only one ranking in the 'bottom 10' is WAS at 27# These teams also rank (similarly) in the top ten for PPG allowed..: #1SEA, #2 CIN, #3 KC, #4 DEN, #5 MIN, #6 CAR, #7 ARI, #8 HOU (8/12 in the top10 again, with WAS being the lowest at #17, which says a lot) and for Takeaways: #1 CAR, #2 ARI, #3 PIT, #5KC, #6 CIN, #7 DEN, #9 WAS (7/12 in the top 10 and only NE in the 'bottom 10) -If we want to look at it offensively results are quite different: It's TRUE that these teams score a lot: PPG #1 CAR, 2 #ARI, 3 #NE, #4 PIT, #5 SEA , #7 CIN, #9 KC, #10 WAS (8/12) BUT the YPG tells a different story #1 ARI, #3 PIT, #4 SEA, #6 NE (4/12 against 3/12; #29 MIN, #27KC, #23 GB) This shows, at least partially, how important the D is when turning the ball over or giving their O a good field position to start the next drive. Without a dominant defensive performance a team has to gain more yards and is more likely to score FG rather than TD, hence less PPG.
