When Dan Quinn left Dallas for the sunny streets of the nation’s capital last winter, the Cowboys had a significant hole to fill on their coaching staff. Quinn had successfully rebuilt the Dallas defense into a force to be reckoned with. Sure, they were prone to massive breakdowns against quality opponents, but overall, they ranked as one of the league’s best, year in and year out.
Complicating matters in the search for Quinn’s replacement was the situation with the rest of the coaching staff. Mike McCarthy was entering the final season on his five-year deal and the rest of his staff was situated to play out the final year of their deals in 2024 as well. The Cowboys wanted their Quinn replacement to join the ranks and similarly play on an expiring deal this season.
As if that wasn’t bad enough the Cowboys made it clear they weren’t interested in being spenders over the offseason either. Whoever came in to fix the defense would have to do so with rookies and the carryovers Dallas had on hand.
It’s safe to say the terms weren’t very attractive and the list of candidates would be somewhat limited as a result. So, when Mike Zimmer’s name came up as the solution, many felt elated such an accomplished coach would even consider the Cowboys, let alone agree to the terms and hop aboard. But that’s what Zimmer did.
Zimmer’s hire didn’t result in parades, but he did receive a fair degree of support from many in Cowboys Nation. As a former coach of the Cowboys, Zimmer had ties to Dallas and as a successful head coach in Minnesota, he had the respect around the league.
Regarded as a disciplinarian, Zimmer looked like he was just what the doctor ordered for the Cowboys. Discipline had long been an issue on the Dallas defense under Quinn, with players freelancing all too often. It resulted in wide swings in run defense and avalanche-like breakdowns against the league’s more nuanced attacks.
Zimmer didn’t just offer discipline and accountability, but he brought a track record of success against offenses like Kyle Shanahan’s. Shanahan offenses have been Dallas’ Achillies heel for years and its growth in popularity has made Shanahan one the NFL’s most prominent coaching trees in the league today.
I didn’t bother to make this chart nice, so I’ll just lead with how I interpret it:
Further right = Better underlying pass defense results against the Shanahan tree of playcallers since 2017
Further up = Better results against all other offenses…
