Depending on your perspective, the defensive line might be returning intact or it might be featuring one new starter.
The position in question is left defensive end. Jason Jones began 2013 as the starter, but he suffered a knee injury in Week 3 that ended his first season in Detroit.
Willie Young took over for the rest of the season, but he is now a Chicago Bear.
Jones will get a chance to reclaim his starting role in 2014, but he will have to fend off some challengers.
Foremost among those is 2013 fourth-round pick Devin Taylor, who flashed some ability in an expanded role late in the season. The 6'7" Taylor could assume a much bigger role in 2014, especially if Jones struggles.
Free-agent acquisition Darryl Tapp projects primarily as a reserve, but he does have starting experience in his journeyman career.
The other three spots are carved in granite.
Ndamukong Suh and Nick Fairley are the men in the middle. The two former first-round picks provide the Lions with one of the most formidable and talented tackle duos in the league, though a little more productivity would be a welcome development.
Fairley is under some pressure as he enters the final year of his rookie contract. As Kyle Meinke of MLive reported, he didn't always play as well as he should have.
Ezekiel Ansah will start once again at right end. Another first-round pick, Ziggy notched eight sacks and two forced fumbles as a rookie, flashing the dynamic potential he offers. He's a rising star.
