This has been tossed around a lot, so here's a thread for it. 

Yannick is a free agent. A slice of the fanbase thinks he's not a good guy, or a bad teammate or something because he wanted out of a bad situation here and had a chip on his shoulder about money. 

Outside of a ill-advised twitter feud with Tony K, he really did nothing wrong. All reports were that he worked hard and was a good teammate. 

He's not a perfect pass rush candidate because he'd be used more situationally than some guys given his run defense issues. 

For those that go on about him not sticking with a team for 3 years, here's a breakdown on that I posted in another thread:

---

I've hashed this out a few times for the resident nonsensical Ngakoue-haturz club over the past year or two.

I think it's simple.

Teams constantly manage cap and positional roster expense. 
Yan is not an every down pass rusher. So he can become a luxury to teams with roster management inflexibility. 
So when a team finds an opportunity to draft a prospect who will be cheaper and play every down - they will replace him. They may also seek a more affordable situation in free agency.

MOST IMPORTANTLY HOWEVER: 
There are also the clear situations of coaching changes and/or scheme fits at various stops.

2020 vikings brought in Ngakoue because they lost Danielle Hunter to a neck injury for a whole season. They also had a struggling and under fire Mike Zimmer apparently at odds with a "threatening to retire" Gary Kubiak about what scheme to run defensively. Hunter came back and they drafted a 3rd round DE as well, so Ngakoue was out. 
2021 Vikes had a new DC. 

2020/21 Ravens - Ravens moved a third rounder picked in 2020 into the lineup for 2021 and selected a DE in the first round. Clearly looking to man the spot affordably. 

2022 Raiders - They went from a Gus Bradley 4-3 to a Patrick Graham 3-4. Bradley clearly was part of bringing Ngakoue in as he had him as a rookie in Jax. Bradley was out, Ngakoue was replaced as well. 

2022 colts - Well lookie here, who was the coordinator? Bingo, Gus Bradley. Now, do I really need to break down the debacle of the colts 2022 season and explain any roster fallout as a result of that regime change? 

Anyway, it may be weird to turn into to a one year per team journeyman, and you may be tempted to say he followed Bradley around the past two years, but he also gave Gus Bradley 19.5 sacks over the past two years, and the team situations laid out above explain roster changes on defense that may otherwise not occur.
