For Jets fans, let me break it down for you.
- Gase's supposed "QB whisperer" mantle is a load of bull. His pupils include Peyton Manning, who he should get literally zero credit for because it's god damn Peyton Manning. He made Jay Cutler look slightly less trash that one year in Chicago. (While completely gutting his best attribute in his arm) And he made Ryan Tannehill, who was already basically the definition of mediocre somehow regress under him statistically.
- He's a "leader of men." He commands a "culture" blah blah blah. Dolphins and other fans like to routinely point out "But the team sucks!." what they fail to realize is Gase had a significant say over his roster. Any guy who didn't fit his "culture" (AKA: guys who disagreed with him) was shown the door and slandered on the way out. Jay Ajayi was labelled as a malcontent manchild by the Dolphins, he gets traded to the Eagles for peanuts. What happens? Ajayi turns out to be a major contributor to a championship winning team and is very well liked in the Eagles room. Jarvis Landry? Sure he wanted to get paid after Gase made him the focal point of the offense. Gase didn't like it, and promptly kicked him to the curb. Landry goes on to have a near 1000 yard season with the Browns. Not a peep about how bad of a teammate he supposedly was. Suh? Makes too money, let him go. Suh goes on to be a two headed monster with the Rams. He benched Reshad Jones, who has been nothing but a gem in his career because he disagreed. Adam Gase is a ****ing douchebag.
- Gase's two biggest accomplishments; beating a bunch of cupcakes on the way to a lame 10-6 season and going 5-1 against Todd Bowles (the guy he's likely to hire as his DC too). That's it.
As Gene already said, the guy is a PR master. Bad, bad hire.
