The way they've reloaded on defense impresses me to no end. Not sure how they do it.
Some epic Bama defensive efforts over the past few seasons:
2016 Clemson: 35 points, 511 yards, loss
2016 Arkansas: 30 points, 473 yards, win
2016 Ole Miss: 43 points, 522 yards, win
2015 Clemson: 40 points, 550 yards, win
2015 Ole Miss: 43 points, 433 yards, loss
2014 Ohio State: 42 points, 537 yards, loss
2014 Auburn: 44 points, 630 yards, win
2013 Oklahoma: 45 points, 429 yards, loss
2013 Texas A+M: 42 points, 628 yards, win
Nick Saban basically plays 1970s era Big Ten football on both offense and defense, emphasizing size and strength over speed.
Good teams have figured out ways to exploit Alabama, especially their defense. Someone will do it again this season. Let's hope that it's Ohio State in the playoffs.
