Zona D outside of Patrick Peterson wasn't much - they lost calais campbell, they lost their rover DB Mathieu. They're so bad they just hired the useless Denver Vance Joseph to be their DC.. They had barely above-average seasons from DB Budda Baker / LB haason reddick / DL chandler jones.
As well, don't look now but someone named Pierre Desir was the 15th rated CB [ahead of Lattimore, Slay and others] in the entire league this season with Indy.
