I did a long write up of the Edge Rushing coaches whom has their head coaches fired and then it did a refresh on me 😔
Short version,
We have a DT coach that came with Hafley from Boston College, so I prefer to call the other coach aht we are talking about the DE or Edge Rusher coach, instead of DL coach.
Bears defensive coordinator has mostly been a DL coach
Patriots DL coach is from the Packers.
Jets DL coach might have Robert Salah (spelling) backing.
Some others that I'm forgetting...
Saints have a pass rush specialist coach that is a former player.
Also not on the DL side, but Saints also have former All-Pro OG Jahri Evans assisting the OL which might be interesting.
Jaguars defensive coordinator Ryan Nielsen has been coordinator or DL coach for the Jaguars, Falcons and Saints in recent years and seems to have a great reputation. If he's willing to be a DL coach again, he might be the most interesting coach, but he also might be over qualified and get a Coordinator opening first.
