Good points, as usual money.
I know I'm in the minority here, but I have lots of issues with DL play going forward, despite the improvements near the end of the season. I understand the scheme calls for quickness and penetration over gap control, but we were consistently washed out at the 1 tech by power inside run plays, and the Mike was almost always engulfed by backside pulling guards or frontside combos. The entire D line struggled with stretch zone concepts; DEs were easily handled by RB lead blockers or lost the edge. We have young talent at LB, especially Thompson and Wax, Jones played well. I am not a fan of Cantin-Arku at Mike, would much rather see Kpogna (who I suspect must struggle with reads and run fits because he is physically a much better player, from my "couch eye view" anyway).
All this to say I am very surprised we have not added at d-tackle/1tech via the portal...
