Just to put your mind at peace (albeit 2 days late)
1. There was/is nothing worrying with how players played on DL. God, Guy, Davis did decent job at what they were asked to do. Barmore played through injury and he was used less. If you actually watch the tape you will see that the game plan was to invite inside run. IDL was wide spread and many times it was 9 TEN run blockers vs 7 box D of NE. Do the math. Both TEN lines did great job, even better than most of the season.
More on all that in separate post. Also if you go back and watch the tape you will def. not want Shelton (or even Branch outside that one season) to step in for God or any other DL of this D for that matter.
We need a 0/1-Tech... and unlike Carl Davis, a good one... I also don't know that I wouldn't want even 2021 Danny Shelton to step in for Davis right now...
