What are you talking about? I'm sorry, but this is just painting the barn blue for the sh!ts of it.
Pete came in here and built a team that SHOULD have won 5 games with an aging Hass and a bunch of no names and has beens on the roster and won 7 games behind the unherladed RB nobody thought was worthwhile. And then he took that 7 win team and that RB and beat the crap out of the Superbowl favorite Saints that year.
Then he completely tore apart the roster and with a bunch of young bucks and a nobody at qb, was still competitive. 7 wins when any other coach could have managed again, maybe 5.
THEN... he drafted Russell Wilson and assembled one of the best defenses in the history of the league and set the NFL on its ear, literally necessitating rule changes and fundamentally changing the way teams approach practice and competing across the league.
He took us to two Superbowls and then unfortunately allowed the entire team to be handcuffed by his loyalty to one RW3.
Peteball was a result of Russ and as is now OBVIOUSLY apparent, so were the overly simple game plans and needing to compensate for having almost no traditional, timing based passing offense with a ground and pound run game.
To compare him to AL Davis, is as misplaced a comp as I can think of. Davis didn't coach. He only had a basic philosophy he subscribed to, not a deep and nuanced way of coaching, teaching, developing talent, and building team chemistry.
You can hate him all you want and try to find reasons to disparage every successful thing he's done. Fact is he built a contender from zero. He then created a beast of a team that should have won 2 titles. And he then unfortunately squandered a legacy with them for the admiration he had for his QB. But even in that failing, he managed to take a QB who couldn't throw short or to the middle of the field, couldn't read defenses, and was never good at passing for 3rd downs through the air and kept us competitive... scratch that... he made us the second most winning franchise in the league over a 10 year span and only suffered a losing season last year because his QB, Russell Wilson went full Walter Kurtz on him and had to be taken out.
He's not without flaw. But the notion that he's just a coach who can't help himself above 500 is just flatly ignoring history and taking those elements of it that match your narrative and sanitizing them of any context.
