Spagnuolo had two stints working with the Giants and head coach Tom Coughlin, who did not make the HOF finalist cut this year.

Without defensive coordinator Steve Spagnuolo, we might not be calling it a dynasty at all. The Chiefs leaned on their defense during their run to another Lombardi Trophy last season, and it was Spagnuolo's defense that kept the Chiefs in all of those close games they won earlier this season.

In order for the Chiefs to three-peat Spagnuolo is going to have to have another great performance against the Philadelphia Eagles, who have Saquon Barkley and the number one scoring offense in the postseason.
