When they fired Saleh their season ended.
Whatever you might say about him, Saleh had his defense playing well on a consistent basis. His "DC" is not a guy who was truly running the D. Now suddenly that "DC" has to actually run the D, or have an even less experienced assistant D coach do it, while also taking over as HC in the middle of a disaster.
With Saleh, the Jets are 5-6 right now, or maybe 6-5 and right in the mix for the 7 seed or even actually in the playoffs at the moment.
Colts are the 8 seed with a 5-6 record right now. Broncos are the #7 at 6-5.
People forget that we always go from "it'll take 11 wins to even make it!" to a 9-8 team playing in the Wild Card. It's like clockwork.
