OFF MAN/DEEP ZONE CB – RICHARD SHERMANThe off-man/deep zone cornerback is much more prevalent in the game as the role isn't nearly as difficult. It allows the defensive back to read and react – reading the quarterback's eyes, seeing the play unfold and reacting accordingly. Being able to see the play unfold allows the cornerback to recognize whether or not his man or side of the field will be targeted and allows the ability to not have to expend energy to cover the route like he would if targeted. That isn't to say the player can take the play off, it's just easier physically and mentally on non-targeted plays when playing off-man/deep zone than it is when having to jam a receiver and match his route all the while.
Since the off-man/deep zone role is used so frequently in the NFL, being in the upper echelon of cornerbacks in this role has serious benefits for the defense. Whether needing to drive quickly on underneath routes or turn and flip hips to match with deep routes, the cornerback that can do both can effectively shut down an entire half of the field. No one has personified this better over the years than Richard Sherman. While he's coming off a major injury needing surgery on both Achilles, what Sherman was able to do in Seattle's Cover-3 system is Hall of Fame worthy. Arguably the best cornerback in the NFL at defending the 'go' route, Sherman is the epitomie of a shutdown cornerback.
Over the course of his career, Sherman has allowed a paltry 53.0 passer rating when targeted, intercepting 34 passes with 62 pass defenses and just a mere 17 touchdowns. He's allowed less than 48.6 percent of his targets to be caught in every season except one when it was just 51.8. Since entering the league in 2011, Sherman has lead the NFL in cover snaps per target twice and ranked third another season. Most impressively, his coverage snaps per reception allowed has ranked him first or second in every season except his rookie debut and his injury-shortened 2017 campaign where he ranked sixth.
