From Grok:
Indianapolis Colts (Defensive Coordinator, 2018–2021)
Eberflus ran a 4-3, Cover 2-based defense with the Colts, emphasizing discipline, run defense, and forcing turnovers over aggressive pass rushing. Here’s how his defenses ranked:
2018:
Points Allowed: 10th (21.5 PPG allowed)
Total Yards Against: 11th (339.4 YPG allowed)
Rushing Yards: 8th (101.6 YPG allowed)
Passing Yards: 16th (237.8 YPG allowed)
Turnovers: T-6th (26 turnovers forced: 15 interceptions, 11 fumble recoveries)
Context: Eberflus inherited a roster transitioning to his scheme. The defense was solid, excelling in run defense and takeaways, with a balanced approach that limited big plays.
2019:
Points Allowed: 16th (23.3 PPG allowed)
Total Yards Against: 16th (346.8 YPG allowed)
Rushing Yards: 7th (97.9 YPG allowed)
Passing Yards: 23rd (248.9 YPG allowed)
Turnovers: T-5th (23 turnovers forced: 15 interceptions, 8 fumble recoveries)
Context: The defense remained strong against the run and in forcing turnovers but struggled in pass defense due to a lack of elite secondary talent. Overall performance was slightly less consistent than 2018.
2020:
Points Allowed: 8th (22.6 PPG allowed)
Total Yards Against: 10th (332.1 YPG allowed)
Rushing Yards: 2nd (90.5 YPG allowed)
Passing Yards: 20th (241.6 YPG allowed)
Turnovers: T-7th (25 turnovers forced: 15 interceptions, 10 fumble recoveries)
Context: This was Eberflus’ best season with the Colts, with a dominant run defense led by DeForest Buckner and a top-10 scoring defense. Turnovers remained a strength, though pass defense was a relative weakness.
2021:
Points Allowed: 9th (21.5 PPG allowed)
Total Yards Against: 16th (343.2 YPG allowed)
Rushing Yards: 10th (109.1 YPG allowed)
Passing Yards: 19th (234.1 YPG allowed)
Turnovers: 2nd (33 turnovers forced: 19 interceptions, 14 fumble recoveries)
Context: The defense was elite in forcing turnovers, with Darius Leonard and others capitalizing on Eberflus’ scheme. Run defense remained strong, but pass defense and total yards were middle-of-the-pack.
Colts Summary: Eberflus’ Colts defenses were consistently strong in points allowed (9th–16th), solid in total yards (11th–16th), and elite in takeaways (2nd–7th). The scheme prioritized stopping the run (top-10 rushing defense each year) and forcing turnovers, often at the expense of aggressive pass rushing, as seen in their mid-tier sack rankings (13th–22nd, as noted in the prior response).
Grok crapped out on me so I don't have the bears tenure yet.
