Jarvis Jenkins is feeling pretty confident these days. And why shouldn’t he? The defensive end is comfortable in Redskins' scheme after making 14 starts in 2012. His surgically repaired right knee is no longer a concern. And, perhaps most important, the game is starting to slow down. “It’s much easier,” said Jenkins, a 2011 second round pick who missed his rookie campaign with a torn ACL. “I have a year under my belt, with me being hurt my first year. So I’m not really thinking anymore. I’m just coming out here and playing ball.” But that doesn’t mean Jenkins is satisfied. Averaging about 38 snaps a game last season, Jenkins showed steady improvement and finished with 25 tackles, including two for loss. ProFootballFocus.com also credited him with four quarterback hits and 14 hurries. But Jenkins did not register a sack - and that still irks him. “Speed of my get-off,” Jenkins said, asked where he wants to get better in 2013. “Main thing I need to work on is my pass rush, so that’s what I’m focusing on this year. Obviously I know I can stop the run; we’re a good team at doing that. We just have to improve on the pass rush and that’s what the D-line is working on.” Indeed, the starters along the defensive line registered only 3.5 sacks last season. In 2011, the unit registered 14.5 sacks.
