The Baltimore Ravens lost some key players in free agency on defense, none bigger than C.J. Mosley, who went on to sign the biggest contract for an inside linebacker in history. They didn’t really replace him, but they did bring in a high-profile defensive addition in All-Pro safety Earl Thomas, formerly of the Seattle Seahawks.
Thomas has admitted that the Ravens’ defense is more complex than what he was used to playing in Seattle, within a defensive framework that largely stuck to the Cover 3 model. Baltimore’s defense has a history of being much more varied, so that is something that he is adjusting to.
