A really simple offense makes the quarterback's life HARDER, not EASIER, in many ways. When defenses get to cheat a lot more by knowing what you're going to do half or more of the time, good execution becomes orders of magnitude more difficult. We can discuss Russell's flaws and shortcomings ad infinitum for the next 20 years, but absolutely NOTHING will change the fact that we had stupidly simple offensive SCHEMING to go along with way too much simplistic play calling almost every year Russell was a Seahawk, and you could still have more disguised offensive schemes even if your QB is a drooling moron. This aspect of our woes under Pete Caroll rests solely on him. Our OL was also not as bad as they looked overall because of this aspect. It's like the difference between walking up an icy winter hill where the sidewalk on the left side of the road was salted, and the right one wasn't, and we just stubbornly insisted on walking up the right sidewalk for years; you're making your life harder for no damn reason.
Russel was not capable of anything but simplistic offense.
He didn't run Schotty's scheme half the time even though it worked.
He ignored what Waldron did and Russ under him looked just like Russ under Schotty.
Then Geno under Waldron looked like an actual drop back read and throw offense that was good enough to garner Geno an MVP vote - Same OC, same 'conservative' HC, entirely different results.
Meanwhile Russ goes to Denver and trues to run a scheme that was anything but conservative and fails. Then he gets an offensive genius to call in plays and famously is forced to wear a wristband because he cant get the terminology down. 15 games in, he is benched, then cut, for failing to run a real offense.
Pittsburgh? Different team, same story.
And say what you want about D Bevell, but when he left here, the offenses he called in Detroit were anything but conservative. In the two years he was there, Detroit finished in the top 10 in passing yards and both years were better than Seattle's passing offense.
The offense was dumbed down for Russ because that's what he was capable of. Since he's been forced to play within a system and actually run non simplified plays, he has been on the struggle bus and this year, tried again to live off script and ignore his OC, just like he did in Seattle.
