Thoughts and Questions on Saban's Defensive Philosophy

A lot of the discussions I've seen and had with people since the Sugar Bowl seem to have been centered around the Saban defensive scheme. As most people know, Saban's defensive scheme is highly complex and built around a whole bunch of moving parts. Here is a good breakdown from an OSU website before the game.

Saban Pattern Matching (11 Warriors)

It feels like the combination of new offenses and the fact that the complexity of the scheme requires both (a)very good - elite corners and (b)veterans who understand the system well enough to not have to think creates unnecessary limitations on who can and cannot get on the field. We are forced to play guys who are less talented but are experienced than younger guys who are all-world talents but haven't mastered the system yet (and Saban is all about trust). The past few years have seen new talent that was clearly better suited to defend certain offenses (athletically) sit on the sidelines as we continued to play older players whose brains understood the schemes but whose bodies could not quite implement it.

So I guess my longwinded, thinking out loud question is : Is Saban's system going to need simplifying and tweaking or will the leaner, faster LB's and more elite secondary players signed in recent classes fix the issues?

Should be interesting to see how things are adapted going forward.

EDIT : I will say, these issues only pop up against elite passing/pass-run option offenses. Against bad/average/good offenses the defense still maintains dominance. But beating elite offenses is what matters.
