How about a different way to look at it:
Running game: RBs are a wash to slightly improved. OL is far more important and you are now missing your very experienced center/blocking coordinator. Morse may not have been an elite talent but he knew what to do. Plus your TEs still can't block much. So at best overall a wash.
Passing game: personnel are similar but you no longer have anyone who will draw a double team. That with lack of receiver speed will compress defenses. Teams may be able to just play man and dare us to beat them because we won't be able to separate. If Kincaid becomes a master zone breaker ala Kelce it would help a lot. So I fear worse, but I hope I'm wrong.
Run defense: if everyone is healthy at best a wash because nothing has fundamentally changed except your safeties may be a liability. Milano can help with splash plays but he's never been a thumper.
Pass defense: clearly worse. The DL cannot consistently generate pressure on its own. I won't believe Miller is back until I see it, and he was less than worthless last year. If both LBs are healthy they are better than what we had in the playoffs and both starters are good blitzers, but...the backfield, oof. The DBs are not quick enough to play man except for Elam, who is a DPI machine and hasn't figured out zone last I saw him. You can't play zone every down. The safeties are the biggest concern on the team as many have stated.
