Quick: name the last time Alabama’s defensive line didn’t have game-changing players...and I don’t mean under Nick Saban — I mean ever. When the “weakest” class of recent vintage, 2012, featured just two current NFL players, you see what some in SEC country take for granted: world-class linemen. And, though it is a trope, it is up front where championships are won. Nothing in the modern game has changed that equation either; it is no coincidence that Clemson and Alabama, owners of the two nastiest defensive lines of the past four seasons, have met in the playoffs for as many consecutive seasons.
