A lot will depend upon Morris and how he envisions what he will run. Warner pointed out the flaw in the scheme which is quick underneath passing. Now that teams have a book on this scheme it will be harder to implement successfully without Morris' own wrinkles. That's why it wouldn't surprise me in the least if he went with a more conventional 3-4 hybrid scheme. He can keep elements of Staley's disguise of the actual play but we also saw how if the DBs make a coverage mistake in their reads the D gets blownup. The scheme is complcated and subject to breakdowns. Morris may opt for something a bit more conventional to make the play more consistent. He's got 2 very good boundary CBs and 3 very good safeties, and an effective 4 man rush. That's a lot to work with.
Either way, he doesn't have to have the #1 defense, because as long as it's a top 5 unit this team would be primed for a run at the Lombardi.
