MLive will chew over each of the Detroit Lions' positions heading into the start of training camp July 30. Today we hit on the defensive line.
Defensive line
Roster locks: Ezekiel Ansah, A'Shawn Robinson, Kerry Hyder, Cornelius Washington, Akeem Spence
Competing: Haloti Ngata, Jordan Hill, Armonty Bryant, Khyri Thornton, Anthony Zettel, Ego Ferguson, Bruce Gaston, Jeremiah Ledbetter, Pat O'Connor, Alex Barrett
Notable departures: Devin Taylor, Tyrunn Walker
Breakdown: The Lions exited 2016 with a clear need for improvement along the defensive line, a unit that massively underwhelmed when it finished 30th in the league in sacks and wasn't tremendous against the run either.
