So apparently our dline guys all have secret nicknames and alter egos

This is elite content from the Chronicle, will copy-paste some of it.

Foley Fatukasi was shocked.
He was asked how he got the nickname “Big Dog,” and though he initially starts to respond, he stops after realizing the question.
“How you know that?” Fatukasi asks. “That’s in-house.”

After a brief back-and-forth, he finally explains. The nickname was given to him by defensive line coach Rod Wright and assistant D-line coach Nate Ollie. Wright and Ollie use the nicknames as motivation for their players.
And it has helped fuel them to be one of the best defensive lines in the NFL.

Wright, who was promoted this offseason to from assistant defensive line coach to the man in charge, said he and Ollie were looking for ways to motivate their players when he thought of giving them nicknames.

By taking on those nicknames, his players would hopefully take on their characters' personas.
Will Anderson Jr., the group's leader, is “The Terminator,” the superhero played by Arnold Schwarzenegger, and a nickname that dates back to his Alabama days.

Hunter is “Cyborg,” mostly given to him by Wright because of his physique, but also his personality, and the fact that he’s not the most well-known superhero.

Edge rusher Denico Autry is “Junkyard Dog,” because he’s a guy you wouldn’t want to meet in an alley and because of his relation to the former pro wrestler.

Edge rusher Derek Barnett is “Deadshot,” named after the superhero played by Will Smith and because he resembles him. Defensive tackle Mario Edwards is “Wild Dog” because of his personality.

Fatukasi is “Big Dog.”

Defensive tackle Tim Settle, has several nicknames. But they mostly call him “Skinny Timmy.”
Edge rusher Dylan Horton is “D-Horton.”
End Jerry Hughes is “Unc” as the elder statesman of the unit.

And defensive tackle Kurt Hinish is “Mr. Reliable.”
“It makes you feel unique,” Hinish said. “It makes you feel good. It gasses you up a little bit.”

Said Edwards: “It’s like (playing) Tekken,” he said of the video game. “You get to pick your character. You tap into that alter ego.”

Each day, before starting the D-line meeting, Wright and Ollie will put up a few clips of the D-linemen making plays. They call it "Rep your style." After showing the player making a play, they'll show a clip of the person's character. The room goes crazy. For players that don't have characters, they'll find other ways to celebrate them.

"It gets the vibes going," Wright said. "The positivity."

You can see it in the celebrations. After a sack, Hunter will put both hands parallel to the ground and act like he’s lifting off like Cyborg. Anderson does the finger wag.
