Mack, Irvin feed off each other, form dynamic duo in Raiders pass rush

Mack, Irvin feed off each other, form dynamic duo in Raiders pass rush

The Buffalo Bills were running right through the Oakland Raiders early in Sunday’s contest, a never-ending assault that took its toll on defenders in silver and black.

That was the case for the most optimistic, steadfast member of that unit.

“We were giving up big plays, and I was frustrated,” star edge rusher Khalil Mack said. “Actually, I was pissed off.”

Bruce Irvin sensed a disturbance in the force. The veteran pass rusher knew how to fix it.  A little pep talk would get Mack going again.

“We feed off each other’s energy. … That dude pulls me up. I was feeling a little down towards the middle of the game, and he was like, ‘Come on. We need you. Come on. Let’s go. He pulled me up and kept pushing.”

That wasn’t the turning point in yet another comeback win. It wasn’t the only reason why defense locked Buffalo down during a run of 29 unanswered points.

It showed how strong a friendship Mack and Irvin have formed since the spring, one that helps get the best out of the other. Bonds formed from insatiable work ethic, one evident even in the offseason program.

“We’re both so hungry to be great that it just brought us together,” Irvin said. “When I got here, we talked right away. Khalil and (quarterback Derek Carr) were the first two guys I sat down with, and I told them I was coming over to play with Khalil, to help turn this thing around and become one of the top units in the league. Khalil and I just bonded quickly, and it was like we had been friends forever. It’s like whole thing was meant to be.”

It has turned out to be a productive pairing. There are 15 sacks, 94 other quarterback pressures and eight forced fumbles between Irvin and Mack this season.

Mack has the bulk of those numbers, especially during a second-half run where he has been outright dominant and jumped into the conversation for defensive player of the year. Mack has been involved in four turnovers the last two games, including game-sealing strip sacks while recovering his own fumble in consecutive weeks.

“You all don’t want to talk to Robin,” Irvin quipped. “Batman’s right over there.”

Irvin has used that line after two home victories in a row. The fifth-year pro is more than Mack’s sidekick. He’s on a roll himself, with sacks in three straight games. He uses speed and agility to create pressure off the strongside edge, dealing with left tackles on a consistent basis.

“I’m in a good groove right now,” Irvin said. “Mentality, physically, I’m in a very good place right now. It’s really showing on the field these past couple weeks.”

Irvin has been a productive defender either making plays on his side or driving traffic back towards Mack. It works both ways, with Mack drawing significant attention that often leaves Irvin in more favorable matchups.

The combination has been impactful, especially on a defense that doesn’t’ get pressure from other sources. They’ve been productive in the clutch as well, with six sacks coming in the fourth quarter. Mack has big plays the last two weeks, and Irvin has a big sack late in a victory over Houston in Mexico City.

The Raiders defense is improving, and having Irvin rushing strong recently helps Mack and the entire Raiders defense.

“He’s always been in a good groove, but there are things going well for this defense,” Mack said. “I’m on the other side, and you have coverage going well. (Opponents) try to do all the chipping and those things that play a factor in doing what we do. The fact that he’s rolling right now is not a surprise.”
