The Jets were one of the worst pass-rushing teams in the NFL last year, finishing the season wtih just 27 sacks, and only 5.5 of them coming from the team's outside linebackers.
Todd Bowles brought in former NFL linebacker Kevin Greene as New York's new linebackers coach, and Greene has already expressed optimism towards his young group of players.
"The sky's the limit for all my kids," Greene told Daniel Popper of the Daily News. "I'm teaching my kids technique and fundamentals not based on athletic ability and skill. It's based on physicality. It's based on drive and desire and want-to and being a student of the game. ... All my kids can really be as good they want to be."
Bowles and the rest of the coaching staff is already seeing the impact Greene has on his players.
"Those guys gravitate towards him and he's a sponge towards them," Bowles said about his linebackers coach. "I think he loves it sometimes more than they love it. If he could get out there right now, he would. But his knowledge in teaching those guys right now is invaluable."
Greene is third all-time in sacks with 160 over his 15 seasons in the NFL. He was inducted into the Hall of Fame in 2016, and earned the reputation as somewhat of a madman because of his incredibly physical style of play.
The 54-year old coach is loud on the practice field, and urges his players to express themselves while on the field.
"I try to encourage my kids to let the love flow, let it flow," Greene said last week. "If you make a good play, nothing wrong with letting a little passion flow and have some passion for your teammates when they make a big-time play. There's nothing wrong with that."
The Jets have a relatively young and talented core of linebackers, including Jordan Jenkins and Darron Lee. Greene has told these young players that they need to have a "hunter's heart" while out on the field.
"Everyone says it, but he really embodies it," Jenkins said. "He wants guys to be relentless."
"He's a nut," Jenkins added. "He really gets excited when guys make plays and when guys are hitting people. He loves all that. He wishes he could do it now. He loves intensity and energy is just oozing out of him."
Greene last coached with Green Bay from 2009-2013, where he helped groom Clay Matthews and won a Super Bowl in 2011.
