Here are some of the things which make us so different.
The Secondary. Both starting corners (Browner, Sherman) are among the tallest, most physical in the NFL. Browner is 6'4 and 220lbs while Sherman is 6'3 and 195lbs. Browner plays the most physical game I've ever seen from a corner. Sherman is physical but is more of a pure cover corner built in the spirit of Champ Bailey in that he's a corner who plays more like a WR. Backing these two freaks of nature are two of the best safeties in the NFL. Kam Chancellor is a devastating hitter at 6'3", 230lbs with speed to keep up with pass catching TEs. He plays in the box a majority of the time and is therefore more like a 4th linebacker on the field. We are able to employ 8 man fronts a lot of the time due to the elite athleticism afforded by Earl Thomas, the ridiculously speedy free safety, with some of the best instincts I've ever seen at the position. Earl Thomas gives us the ability to run single high safety looks while allowing our corners to play tight and physical at the line.
The linebackers. While this crew is overshadowed by the elite play of the secondary, they are quietly playing some really damn solid football. We have a rookie starting at MLB in Bobby Wagner, and his play has been stellar so far with flashes of elite ability the past couple games. We grabbed KJ Wright in the fourth round of the draft last year and he was able to replace first round bust, Aaron Curry, by midseason. Now, KJ Wright is becoming the player we all should have had in Curry. He is a terror who makes plays sideline to sideline. He enjoys making running backs cry three yards behind the LOS. Adding age and experience to the group is Leroy Hill, who has always been solid.
The D-Line. These guys are monsters. Arguably, the most unique thing about our defense is the way the defensive line plays in our base 4-3 look. Red Bryant plays a sort of hybrid "5 technique" role, similar to that of a defensive end in a 3-4 scheme. Opposite him is Chris Clemons, our rush end, with Brandon Mebane manning the nose (in spectacular form this season), with Alan Branch manning the 3 tech spot. Bryant, Mebane, and Branch all frequently occupy two blockers while Clemons terrorizes the quarterback and makes plays in pursuit. I won't even get into the substitution packages since there are so many different pressure looks, overloads, and new wrinkles involving Bruce Irvin and Jason Jones.
