The Seattle Seahawks have fielded the NFL's No. 1-ranked defense in each of thepast two seasons. But during the offseason, the 'Hawks lost defensive coordinator Dan Quinn (now the head coach in Atlanta) as well as key contributors like Byron Maxwell and Tony McDaniel. And the unit is still waiting for its dynamic safety duo to hit the field in game action: Earl Thomas is rehabbing from offseason shoulder surgery, while Kam Chancellor is holding out.
Now, obviously, Seattle's defense still could -- and should -- be one of the NFL's best in 2015. But it's plausible to think somebody could knock the Seahawks off their No. 1 perch in total D. Looking across the league, which team has the unit to challenge Seattle's reign of defensive terror in 2015?
Buffalo's front four is as good as it gets in the NFL. This quartet gets after the QB and, in the process, forces fumbles. That's huge. And don't forget: Veteran DE/DT Red Bryant is now in the rotation, and he's a solid player and leader. The linebackers and guys in the secondary will be very aggressive, which will leave them vulnerable, but it also puts them in position to make plays. The Bills were one of the top teams in terms of forcing turnovers last season, and that should not change.
A couple of sleeper defenses that should be in the mix for the No. 1 spot, along with the
Cardinals. Oh, and I do not think that the
Lions' unit is just going to fall apart without
Ndamukong Suh, either.
The Cardinals' defensive line is fantastic -- Calais Campbell never gets the respect he deserves. Patrick Peterson is fully healthy, something the game-changing, playmaking corner never was last year. And Tyrann Mathieu should be back to 100 percent, as he was during his rookie year (before he blew out his knee). The Honey Badger wrecks offenses with his nose for the football.
Houston is so well-coached and has the game's best defensive player in
Jadeveon Clowney is back on the practice field, and I still believe he can reach his potential and upside.
Brian Cushing is healthy, which is huge for this unit. Lastly, the defensive backfield is improved, as the
Texans spent their first-round pick on cornerback
My other nominee is Buffalo (fourth-best D in 2014). The
Bills have an outstanding and seasoned front four that can rush the passer and defend against the run. But how good is their secondary? Another sleeper team to look at is the
St. Louis Rams, led by dynamic pass rusher
Most of the key players, including those on the
Mario Williams-led D-line, are back in 2015, while second-round pick
Ronald Darby should add to the secondary. Finally, the defense should get a boost from both an improved offense, which should reduce the amount of time the defense is on the field by about two minutes per game, and the fact that
the Bills' final two contests will be at home, likely in the kinds of conditions that favor defensive play.
[Ndamukong Suh](/player/ndamukongsuh/496861/profile)'s presence alone completely changes the line's ability to push the pocket and disrupt opposing passers. To help, the game's most dominant behemoth east of [J.J. Watt](/player/j.j.watt/2495488/profile) is flanked by [Olivier Vernon](/player/oliviervernon/2533534/profile) and the perennially underrated [Cameron Wake](/player/cameronwake/2506314/profile). [Brent Grimes](/player/brentgrimes/2506861/profile), meanwhile, gives you one of the AFC's top cornerbacks in a secondary that will benefit from the constant attention placed on Suh and Co. up front.
"I don't have a problem saying this, but I think personally we have more talent than we had in the No. 1 defense last year in Detroit," Suh said this week.
I still see Seattle as the unit of choice, but no team added a bigger chip on defense than Miami. Suh will wreck game plans from wire to wire.
