With the change in scheme comes a change in style of player. “You need different body types on the defensive line. You need different linebackers," Shanle told the WWL podcast. The biggest thing the Saints need to address is the outside linebacker position. It’s the first position that comes to Shanle’s mind in a 3-4 defense. For the Saints, that’s not a good thing.

“I think number one thing when someone say they’re going to a 3-4 defense you better have outside linebackers.” Shanle described the necessary players as guys who can “stand up and get after the passer then be athletic enough to drop back in zone coverage.”

Defensive end Carl Granderson has been with the New Orleans Saints for the entirety of his six-year NFL career. He's gone from an undrafted rookie out of Wyoming in 2018 to one of the team's most consistent defensive players.
Granderson has been a defensive end in the Saints' 4-3 system his entire career.
At 6'5" and 261-Lbs., he has the length and athleticism to be a stand-up rusher in Staley's 3-4 scheme. Despite his lanky frame, his power and strength might also be adequate enough to be an end on a three-man line.
