Von Miller has said that his Denver Broncos teammate Derek Wolfe can have a similar impact to J.J. Watt's in his second year in the NFL.

The defensive end, who was a second-round pick in last year's draft, made 40 tackles in 2012, including six sacks.

Miller, who was the team's sacks leader last season, told the Broncos's official website: "Derek Wolfe had an amazing rookie year. I think everybody knew he was destined to be [a leader] right when we first brought him in. He's just a worker.

"His sophomore year, I think he's going to have an amazing year. You can just tell by the way he's working on the field. It's hard to go against him. I'm all for him.

"I talked to him about [Houston Texans defensive end] J.J. Watt and the jump that he had from year one to year two. I think he can do the same type of stuff. I think you just keep working hard. I think he'll have the same type of effect for our defense."

Watt was named the NFL's defensive player of the year in 2012.
