PHOENIX — The Steelers could take lessons from the Seattle Seahawks on how to build a great defense.
They are two defensive ships passing in the night, the dominant defense of the first decade of this century that got old and slow as it tries to transition back to where it once performed versus the most dominant defense in the NFL the past two seasons.
But several opportunities for the Steelers to keep adding youngsters and swapping out old players to keep those great defenses viable already slipped past them while the Seahawks took advantage.
