I think Bama is playing a (Mike) Shula style offense, the O line doesn't have it this year, and the players aren't in it. I also credit LSU's players for their win.
As far as Les Miles is concerned (stop reading here if you are pure X's and O's):
When I was a kid of 9 or so I got the bright idea to steal one of my Dad's .357 bullets and make a rocket. I taped the lead, none of the casing, of the bullet to a pencil. My idea was to balance the pencil on a street sign, and shoot at the bullet with our bb guns until the bullet went off - the idea being the bullet would fire, and the pencil would take off like a rocket.
It worked pretty much how you'd imagine. First, we couldn't hit the bullet from the relative safety of the ditch we were were using as a berm, so we inched closer and closer trying to make the bullet fire.
When we finally achieved success, the bullet of course exploded with a deafening roar, with nothing left under the street sign but shards of pencil and pieces of tape.
No glorious pencil-rocket.
I received the worst belt-whipping of my young life shortly thereafter. My point is, I think if Les Miles tried this, the pencil would fly.
