Why did Spagnuolo stink as Saints' DC? (merged)

I don't know about now ... but back then, Spagnuolo's defense was heavily dependent on having the right kinds of players. Specifically, his defensive front seven had to get consistent pressure on the QB with only four rushers
Well, looking it over ... six-time All-Pro DT Chris Jones is a nice centerpiece for the Chiefs. Dude is going to be one of the All-Decade DTs and waltz into the HOF.
