I'm sorry, I just see people picking at the margins, around the edges. "We need a new kicker, a 'stud' DT, a different DC, a new coach, an edge rusher" and on and on.
You can't be loaded at every position, and reportedly this team was pretty stacked going in. How many more "studs" do you need at how many more positions before someone realizes that's not the problem?
Coaches? Okay. But there's always a messiah HC out there who will come in and somehow carry the team to the promised land. Hasn't happened for the past quarter-century.
Garrett is a toad and a loser, and Marinelli should be riding on a golf cart in a retirement village somewhere. But they're just temporary symptoms of a chronic disease. The disease is the owner who keeps those coaches there, and will hire the next symptoms -- if it ever comes to that.
If the patient is suffering from chronic internal bleeding, the answer isn't a band aid.
