Rob Leonard has more responsibilities now than he’s ever had in his 13 seasons as an NFL assistant coach.The Las Vegas Raiders’ defensive coordinator is getting a chance to build and implement his system for the first time; he’ll make his play-calling debut in the fall. However, while Leonard’s duties have multiplied as a first-time coordinator, he’s finding parts of his new job are less active than those of old.“Feeling like not having anywhere to go during individual has been different,” Leonard said in his first comments since his February hiring. “I feel like I should be bouncing around, but that’s just my personality … I’m a higher energy guy out there, as you can tell.”Leonard’s vigor for coaching has been palpable during offseason team activities. While the longtime position coach no longer has a specific drill to run during individual periods, he can’t help but get involved.Leonard will stand on sleds for his defensive linemen and pass rushers, hold bags for his linebackers to hit and run routes for his defensive backs to cover. He’ll even serve as the ball carrier in unit-wide pursuit drills, running downfield as his players feign tackles upon him.His actions exemplify the effort he wants his defense to play with. Leonard said he wants his group to be aggressive to a fault. He feels like he’s viewed as “a little crazy” for his philosophy, but he believes an attacking mindset is crucial for defensive success.“I would like them to play fast, even at the cost of a mental error,” Leonard said. “I don’t like to see hesitation on the field, so even if you’re unsure, make a decision and go and let us coach. Let us do our job, but I don’t want any slow blinkers out there.”The approach is one that Leonard has employed since he walked on at NC State as a linebacker. And it’s one the Raiders need to adopt following a season during which they were among the league’s worst in getting after the quarterback and creating turnovers. After Klint Kubiak promoted Leonard from defensive line coach this offseason, Leonard has vowed his group will embody his methods.“Style of play, man,” Leonard said of what will stick out about his defense. “I’m going to coach the defense like I coach the D-line. I still do the same things I do. Not going one-for-one, attacking the ball, effort in pursuit. We start there, but that’s always got to stick out, and a product on the field that you know what it looks like.”While it’s clear Leonard will emphasize playing with reckless abandon, there’s still a lot to be learned about how he’ll run his unit. Here’s more on what organized team activities have taught us about Leonard and his scheme.
