Dareus won't be the first or last player associated with Ryan's scheme to accuse him of being complicated. Ryan had his most success in 2009 and 2010 -- a time where he loaded up the defense with heady veterans who were already accustomed to the terminology. Linebacker Bart Scott and safety Jim Leonhard were brought in to pilot the scheme and translate its complexities. Veterans like former Raven Trevor Pryce and all-time great Jason Taylor followed suit. His best defensive players had a graduate degree in Rex-ology, or, in the case of someone like Darrelle Revis, they were asked to do something specific (like match up on the other team's best receiver and follow him everywhere).
