Very possible. Always seemed strange that he used the same plays and formations that McElwain used and I've heard Saban make the statement that you couldn't teach proper defensive techniques in practice using a hurry-up spread offense.
Also possible that the Auburn game showed Saban he needed to go in another direction offensively (which he's never done before). Most of the best high school quarterbacks are coming out of spread systems and it's getting hard to find the pocket passer that can compete with them. Not a whole lot of Peyton Mannings or Tom Bradys around.
I don't think a drastic change is in order (it's not like Alabama has fallen off of the map) but a tweak or two wouldn't hurt. At least put a fullback in the backfield like LSU does at a minimum.
Yet both of those teams in the NFL run shotgun up tempo offenses, just saying
Here's the thing. Up Tempo spread offenses can run the same routes as pro style or west coast. Its just window dressing, and a little tweaking. Look at USC when they had Reggie Bush. They were single back 3 wide outs + TE. Pro style, they power ran with and they threw it all over the place. Spread is just a loose term for using the whole field, primarily with quick screens. It use to be power run, get the safeties up, stretch the field vertically. Now its quick hits up the middle, hit the edge with speed, force the inside DB to commit to the edge run, and then throw sideline for quick screens, then its also stretch the field vertically.
The key to any offense is pick an identity, and go with it. If Saban wan'ts to run a power football with a fullback, then he should commit to it. The worst thing you can do is try to do something they are not.
Its what drove me crazy with Ohio State. When they fed Hyde all year, would run him 12 times in a row in the 2nd half in a lot of games. Just wear out defensive lineman. Yet they get into the Big Ten title game, and the Orange Bowl, and they key up design runs with Braxton Miller. I mean, WTF. Didn't do that all year long, except for two games. They had a RB who averages 7.5+ yards a carry, and they give it to the QB to run. Hyde falls down for 3-4 yards, and if he gets on a linebacker or DB, he isn't going down till another 4 yards. The worst thing a team can do is do something they are not.
