The first two seasons of Jadeveon Clowney's NFL career haven't gone the way he wanted.

But don't call him inconsistent.

"I don't know if he's been inconsistent on the field," Texans general manager Rick Smith said Thursday. "When he's been on the field, he's been pretty disruptive and pretty impactful."

Clowney, the first overall pick in the 2014 NFL Draft, played in 13 games and finished with 4.5 sacks and six batted passes.

"What you see when you see him on the field, you see productive play," Smith said of the outside linebacker.

Speaking at a 2016 NFL Scouting Combine press conference inside Lucas Oil Stadium, Smith explained that better luck will go a long way toward Clowney making a bigger impact.

"Hopefully the guy has had his share of injures and that he will have an opportunity to play and play for an extended amount of time," Smith said. "Some of those injuries, it's not like he's getting hurt because he's not working. The nature of the injuries that he's had are not such that it's an indicator that the guy's not been conditioned or ready to play. It's just the nature of the game."

In his first five months with the Texans, Clowney dealt with sports hernia surgery, a concussion, and a meniscus tear. In late November of 2014, he was placed on injured reserve after a microfracture surgery.

Clowney rehabbed from that and was back on the field in Week 1 of 2015. He battled a foot injury last season, which kept him out of three games.
