How do you figure this? Zimmer's defenses stunk so bad 20 years ago with Dallas that they broke shame records that still stand.
He's merely taking back up right where he left off. This is why you pay attention to a guy's results. Only an idiot would have hired Zimmer in 2024, and Jerry was the only one to even offer him a job in the NFL.
Just like only an idiot would have signed Zeke in 2024, and again, Jerry was the only one to offer him a job. There's a distinct pattern of results with Jerry.
When a guy proves he sucks, it's not going to change. That's why nothing changes with Jerry at GM, because he's proven conclusively that he sucks. That's also why the defense sucks under Zimmer. Zimmer as Cowboys DC has done nothing but produce crappy defense.
