The chase is on for more productivity as well as more depth from West Virginia’s defensive line, and though we know the identities of the starters and a few of the potential backups, we don’t know much about a history of success beyond a few names — because there isn’t any.

The Mountaineers will need and find players in reserve, but it’s fair to say a lot of the success on the defensive line is entrusted to the known commodities.

Nwachukwu, a 6-foot-2, 275-pound reshirt senior, said Wednesday he, Brown and Howard are up to the task.

“We have experience and we know it,” Nwachukwu said. “We know other guys are going to feed off us, so we have to set the tone. That’s definitely a key.”

As is unlocking Nwachukwu’s sack potential. At one point, Holgorsen boasted he had the Big 12’s returning sack leader in the senior, but that’s only if you narrow the search to conference games. Still, Nwachukwu had a more-than-respectable 8.5 sacks last season — and is seeking more in 2016.

“I don’t have a number in mind, but I know I have to get more than I did last year,” Nwachukwu said. “I’m aiming for double digits. Anywhere in double digits I’ll be satisfied.”
