Ultimately, yes. They failed at the highest level.
But it was still failure.
As bad as Schottenheimer? No. But he couldn't hold a candle to Walsh, Parcells, Gibbs or Johnson.
Any season that ends without a championship is a failure. In fact the farther you go without winning it all is a worse failure because it cripples your drafting for no benefit
Dont care about their PBP guy. Care about their scouting/management group. They obviously know how to draft the OL/DL and skill positions too
In other words, they're competent
