They underachieved this year and despite throwing tons of resources at it (and in my opinion still have good tackles and RB's) we got our arse kicked in the trenches which has been an issue for years. When your identity is solid defence and running game and you can't do either and can't seem to fix it then your in trouble. Biggest insult is being called soft and that's exactly what the seahawks were this year. I also get the vibe Pete was fine was Geno and Lock which ownership maybe don't agree with.
Bad stat for Pete was that Seattle ran both the fewest Offensive plays and played the most Defensive snaps.
Meaning Pete's philosophy of run the play and play great defence was not working. Not possessing the ball enough to wear down the opposition and thus resting the D, plus the D not able to get off the field.
Cliff Hurt, had like 6 games where the Defence only forced the opposition to punt 1 or 0 times in his tenure. Prior to him, under Carroll's defence for over a decade let that happen to them fewer times.
Probably also didn't help Pete that Adams his target, has been hurt and is on a big contract and they gave up like pick 9 for him in 2022. (1sta nd 3rd were fine, but that extra 1st hurt).
Similar to BB, Pete had a lot of power and the major moves he made didn't work.
Harvin, barely 2 years.
Graham, killed the identity of the team since Graham could not block and Russ didn't work the middle.
A couple of trade downs in the draft to pass on CB Alexander to gain an extra 3rd (since they dealt for S. Richardson DT and Brown OT) so wanted a pick back. Only to draft Penny over Chubb (who fit Seattle's pound the rock style better). And trading back to take McDowell, vs Ramczyk a RT who has made the Pro Bowl and fill a need. None of the extra picks they got made any impact. And the Adams trade.
