Last summer, I wrote that Mack's combination of speed and power is unrivaled, and his 2018 numbers (10 sacks, six forced fumbles, four passes defensed, one INT returned for a TD) support my argument. The Bears immediately fielded one of the best defenses in the league when they traded for Mack, and he's elevated the play of those around him. A consistent game-wrecker, Mack has again made a legitimate case for Defensive Player of the Year, the award he won in 2016.
Hunter has been the star of Minnesota's defensive front and is on pace to get a career high in sacks (with 12.5, he's on track for 15). He has great lean and a knack for getting to the quarterback. It certainly feels like a passing of the torch on Minnesota's D-line.
It's refreshing to see Watt back on the field every week -- well, unless you're part of an opposing offense. The three-time Defensive Player of the Year is back to his normal self after two injury-interrupted seasons, with 12.5 sacks and a career-high five forced fumbles on the year.
Donald has hit another level since signing his new contract. The league's sack leader (16.5) through 14 weeks, Donald is a generational talent and, in my opinion, should be this year's Defensive Player of the Year.
Casey, who's made the Pro Bowl in each of the last three years, has thrived under first-year head coach Mike Vrabel, with seven sacks and 11 tackles for loss. He's a big reason why the Tennessee defense ranks fourth in scoring as one of five teams giving up less than 20 points per game.
Wagner is one of the best middle linebackers in the league and has been for quite some time. A game-wrecker in all phases -- as he demonstrated Monday night vs. Minnesota -- the veteran has elevated the play of Seattle's new-look defense. Wagner recently recorded the first pick-six of his seven-year career.
The Colts rookie leads the NFL in tackles (135) by a wide margin -- the next-closest player is Green Bay's Blake Martinez with 118. On top of being a tackling machine, Leonard has seven sacks, four forced fumbles (two recovered), four passes defensed and one INT. He's going to be a staple of the Colts' defense for years to come.
Miller has recorded at least one sack in each of the last five games and sits second in the NFL in sacks (13.5). This season marks his fifth straight with 10 or more sacks, which is no surprise when you consider Miller's ability to get off the ball.
Jackson has been a ballhawk in the Bears' secondary with five picks, two of which were returned for touchdowns. He has been a huge impact player in Vic Fangio's defense, which leads the league in takeaways (34). On a side note, Chargers free safety Derwin James should have a spot in this year's Pro Bowl. It was a toss-up between Jackson and the stud rookie for this spot, but both should make an appearance in Orlando -- if their teams aren't playing in Super Bowl LIII.
Adams has been a bright spot for a struggling Jets unit in 2018. Among all safeties playing at least 80 percent of defensive snaps, Adams has allowed the lowest reception rate (47.4) when targeted, according to Pro Football Focus. He's a physical presence in the secondary who has a very good shot at making his first Pro Bowl.
Peterson has made the Pro Bowl every season of his NFL career -- and this year should be no different. Peterson has added three more picks to his name this season, while allowing a 69.0 passer rating when in coverage. In a season full of growing pains for the Cardinals, they were smart not to trade away one of their best players.
