I think the defense is a bigger indictment of McAdoo than anything. The suspensions and injuries to key players have really hurt that defense, but the pieces are still there. That defensive line has potential off the charts and DRC, Jenkins, Apple, Thompson, and Collins still make up an absurdly talented secondary. I think the linebackers need an overhaul, but who knows more about linebackers than someone from Baltimore?
At quarterback, you'll return Manning, have Webb, and have a top 5 pick in a draft with Allen, Rosen, and Darnold. He could very easily walk away with one of them. There's pieces to work with in the passing game with OBJ and Sheppard(sp?) and Marshall if he wants to return. Sure, the offensive line definitely needs some tweaking, but if they can find a legit LT and slide Flowers over to RT, I think the line could start to look a lot better.
I don't know; I think the situation could be appealing for a soon to be GM.
You are correct- I don't think DeCosta is too caught up in it at the moment.
