Trent Baalke’s final two seasons as 49ers general manager brought defensive linemen to the organization with the club’s top draft picks.

And, for that, new 49ers general manager John Lynch said he is grateful.

Arik Armstead and DeForest Buckner may have been chosen when the 49ers’ base defensive alignment was a 3-4, but Lynch said the two Oregon products are versatile enough to thrive in the new system defensive coordinator Robert Saleh will install.

“I think they fit very well,” Lynch said Tuesday on 95.7 The Game. “And that’s one thing I think I want to make sure (to say) because I really believe it, I think Trent Baalke did a great job of getting guys that, yes, they were picked for one system, but I think they transition very well to our system.”

Buckner appeared in 15 games as a rookie after Baalke selected him with the No. 7 overall pick. He ranked second in the NFL among defensive tackles with 73 tackles and was fourth among rookies with six sacks. Buckner was chosen to the All-Rookie team by the Pro Football Writers of America.

Armstead, selected with the 17th overall pick in 2015, recorded 2.5 sacks in eight games last season. He sustained a shoulder injury during training camp and finally underwent season-ending surgery in November.

Buckner and Armstead may be asked to play different positions but they will also be taught to play a different styles this season, Lynch promised.

“They were very much in a read-and-react posture last year,” Lynch said. “I’m excited to cut them loose. When we say ‘aggressive,’ it doesn’t mean that we’re blitzing every play. It means we’re getting off the ball. At the snap, we’re taking the fight to them. And I think these are guys who fit what we’re going to do very well. We’re excited about it.”

 

The 49ers last week hired defensive line coach Jeff Zgonina, who played 17 seasons in the league. Zgonina served the past four seasons as an assistant defensive line coach with Houston (2013-15) and the New York Giants (2016).

“They’re going to be coached hard,” Lynch said of the 49ers’ defensive linemen. “They’re going to be asked to sprint to the football, wherever it is. That doesn’t just come natural. Those are habits that you have to pick up.”

Every defensive player currently on the 49ers’ roster was brought to the organization to play in a 3-4 defense. Lynch downplayed the practical importance of the team’s defensive label because of extra defensive backs being deployed against three-receiver personnel groupings.

“Seventy- to 75-percent of this game now is played in sub or nickel,” Lynch said. “At that point, that’s kind of out the door. It’s can you stop the run and, then, can you go get the guy throwing the football and bring him down? We think both of those guys have great potential to do that.”
