If the Minnesota Vikings don’t know it by now, it’s not a bad idea to listen to Andre Patterson.

As a longtime defensive line coach who recently was promoted to co-defensive coordinator, Patterson has made a career out of transforming overlooked prospects into terrorizing pass rushers.

His biggest success story has been Danielle Hunter, an NFL star the Vikings picked up in the third round in 2015. And Patterson thinks he’s found another hidden gem in fourth-round draft pick D.J. Wonnum.

“That was one of Andre Patterson’s guys,” general manager Rick Spielman said after the draft. “He really he wanted to get his hands on him and work with him.”

It’s clear the Vikings have high expectations for Wonnum whenever they can get him to TCO Performance Center. It’s also clear Wonnum has equally high expectations for himself.

“You know, Coach Patterson saw something in me that were some of things he saw in Danielle Hunter,” Wonnum said. “I’m just excited to be able to learn from one of the best pass rushers in the league right now.”

It’s not hard to see why Wonnum is drawing comparisons to Hunter. Just look at their measurables.

As a polarizing prospect out of LSU, Hunter entered the league at 6 feet 5 and 252 pounds. He had 34 1/4-inch arms and 10 1/2-inch hands.

As a polarizing prospect out of South Carolina, Wonnum is 6-5, 258 pounds. He has 34 1/8-inch arms and 10 1/2-inch hands.

You’d struggle to create a better clone in a lab.

That said, Hunter has gone on to become the fastest player in NFL history to reach 50 career sacks, while Wonnum isn’t even a lock to make the team out of training camp.

While there’s a lot to like about Wonnum from a physical standpoint, he needs to refine his technique to make an impact at the next level. Which means the comparisons to Hunter should probably stop.

Not that Wonnum is backing down from the challenge. That much was clear simply from talking to him after the draft.

“It depends on the makeup of each kid,” Spielman said. “I think with this kid he’s looking forward to that challenge. I think when he hears a comparison like that to a Danielle Hunter, he says, ‘This team just drafted me and believes that I have potential to be something like that.’ And I think it’s going to make him do everything he can to try to reach that very high goal.

“I also know that (Coach Patterson) is going to be wired that way,” Spielman added. “It’s like, ‘Hey. I’m really standing on a table for this kid. I’m going to do everything I can to get this kid where his potential can take him.’ ”

If he can reach his potential, the Vikings might have found their next dominant pass rusher.

“It’s still kind of surreal,” Wonnum said. “Just comparing me to him, it kind of, like, opened my eyes to see something, like, ‘Man, I’m going to be a beast from the league.’ “
