As Saban tells it, he used to teach backpedaling until he was with the Cleveland Browns with Bill Belichick. The ownership signed the legendary Everson Walls, who, much to the dismay of the young defensive backs coach, Saban, ran about a 4.8 forty yard dash and simply could not, under any circumstances, backpedal. He was awkward, couldn’t accelerate, and there were other guys on the roster much better at backpedaling.
Walls also, however, was being paid significantly more than his coach, and it was clear from the ownership that Walls would be starting. He also, it must be said, was still a great player, and just happens to still rank 10th on the all time list of most interceptions in NFL history. So
Saban began teaching his now famous “shuffle” technique, rather than the traditional backpedal. There’s a good deal to it, and it can adjust depending on the receiver’s exact release, but essentially it is a three-step shuffle technique, at which point the defensive back may break on a short route or can turn and run and play the receiver down the field.
Complementing this is that Alabama’s cornerbacks spend about 90% of the game in a press coverage position, from which they either stay in press or can bail to a zone or off-man position. They do this because it threatens the offense and helps take away screens and quick passes, and
they feel that if a defense doesn’t press it’s a huge advantage to the offense who is simply throwing routes on air. I have to say that having excellent corners like Saban has had at Alabama helps, but, as more of an offensive guy, I would much prefer my corners to show a lot of press (even if they bail a lot) and use the shuffle technique as opposed to the backpedal. There’s nothing easier than seeing a bunch of corners lined up at seven yards backpedaling at the snap; you can run just about anything at that, and they simply will not be able to react quickly enough.
