Nick Saban is perfect for Alabama football -- because he IS a defensive-minded football coach.
The evidence is plentiful that if Bear Bryant won all eleven games each by a score of 3-0, he would prefer that over winning all eleven by, say, 39-28.
Remember the Archie Manning-Scott Hunter game of 1968? I forget the exact score, but each quarterback threw for over 500 yards, and after the game all Bear could say was something like, "That was the worst played game I ever saw."
I don't know much about Coach Frank Thomas, who was Bryant's mentor, nor do I know much about Wallace Wade. But Bear Bryant preferred that his defense gain excellence before his offense scored much at all. He actually said something like this: "Defense wins; offense is for TV."
By the late seventies, the offense AND the defense were cranked up, with the likes of Major Ogilvie and Tony Nathan, but still the defense determined the identity of Alabama football. In fact, the Wishbone is an offense, IMO, that looks like a defense. It is rock-'em, sock -'em football, any way you cut it.
Bear had the great quarterbacks in the sixties -- Namath, Stabler, Hunter. But he was dissatisfied with that style of football. His favorite quarterback was Pat Trammell, whose passes often looked like dying ducks. It was Pat's tough-mindedness that Bryant liked.
Oh yeah, we wish the media would exclaim about Alabama dominating their opponents, like Oklahoma or one of those other scoring machines, and instead Alabama has been grinding out the wins with little fanfare.
If they keep doing that, Alabama wins the National Championship. The Bear would be pleased.
