Mike Daniels has said that "relentlessness" has helped him become the Green Bay Packers' sacks leader this season.
The defensive end, who is in his second season in the NFL, has made eight tackles and 4.5 sacks so far in 2013.
The 24-year-old told the team's official website: "It's just the result of my work in the off-season. I mean, I just had to keep pushing. It's definitely an accomplishment but that could change any week, so I just need to continue to press forward.
"I spent [the off-season] really rehabbing my shoulder. I stayed out here and watched a lot of film, worked out and changed my diet. I can really see the improvements right now. Relentlessness, so it would be a combination of quickness and strength.
"Every attribute that you can think of that you would want to play with is something I try to apply to my game. I just think when you play with a motor or relentlessness, a never bending or breaking will, then eventually you'll break someone else's will."
The Packers face the New York Giants later today.
