Throwing stats out the window and just using the eye test I will say this year's front 7 very well could be the best ever. I don't ever really remember so many Sacks, QB hurries, TFL's via gang style, and Intentional groundings. They just absolutely HARASS opposing QB's and RB's behind the LOS. It's pretty amazing to watch.
But I'm still crazy impressed by the 2011 secondary though. Giving up only 111 ypg.....man Barron, Lester, Milliner, and Dre were Bad BAD men back there. Milliner and Kirkpatrick pretty much blanketed WR's and weren't guilty very often of not playing the ball. Barron and Lester were always prowling around back there looking to de-cleat a WR IF he made a catch. Plus my goodness could Barron and Kirkpatrick come up and 'help' in run defense. They both could just BLAST RB's with bone crushing tackles. I LOVE that squad.
If you could take 2011's secondary plus 2016's front seven......whew.....good luck to anyone trying to score.
