The scheme is similar to that in  seattle, but in seattle they run a lot more press coverage to disrupt the timing of the routes whether they drop into zone or run man under.  The biggest difference is that in either alignment, you are running a single high safety.  If the corner is technically playing deep third on the outside or straight man against the receiver is irrelevant because they don't have a dedicated safety to a half of the field as in cover two.  In seattle they have a kid named earl Thomas, who like Richard Sherman QB's don't like throwing at and when they do has the range to make plays on the back end.  I love Winston guys toughness and I like josh evans versatility, but they are a far cry from the prototype FS that you would want to run this scheme.
