My own personal opinion of all this is, our defense played the greatest Super Bowl game EVER! I think it's simply inarguable. Beating down the statistically greatest offense of all time, in the fashion our defense did it, is simply, unarguably, the GREATEST defensive performance in any Super Bowl ever, in my opinion.
I don't think it was the greatest regular season defense ever, but it WAS top five for sure! It's at least in the conversation with the Ravens, Buccaneers, Bears, Steelers and whoever else you may want to throw in there. Personally I'd put them third, behind the 2000 Ravens and 85 Bears, but ahead of the Buccaneers and Steelers.
I would lean towards saying the 2000 Ravens defense was the best I've ever seen for a single season, they pitched more shutouts, and had so few points scored against them, I just have to give it to them, though that 85 Bears defense was absolutely BRUTAL, and I would probably put them a very close second on that list, so close that you could basically call them 1a and 1b.
The Steel Curtain defense was the best I've ever seen for sustained success and in terms of overall talent. Those Steel Curtain defenses had literally 7 out of their 11 defensive players in the pro bowl regularly, and deservedly. So though I don't think they put together the top season ever, I give them the best defense of all time, simply for maintaining such an extremely high level for multiple years.
As for the Russell Wilson debate, all I know is that, while it's true he's surrounded by some very good players, especially on the defensive side, he also had to deal with a statistically terrible offensive line for most of the year, and while Seahawks fans know that our receivers are better than Chris Carter wants to admit, they're also not outstanding by any stretch. When you throw in the relative lack of production from the tight end spot, our total receiving corps looks almost pedestrian.

Still, in the end, Wilson has done exactly what's been asked of him in the offense, he's put aside his pride and put a leash on the desire ever QB has to go out and wing it, (something he is absolutely capable of doing if he were asked to though), and has played controlled smart football, and won doing it.
Personally I wouldn't trade him for Andrew Luck. I think he's the perfect "point guard" QB for our system. He'll always be underrated because of his size and because of what he's asked to do, but we Seahawks fans will always be able to point to certain things such as, since he arrived we've not lost a single game by more than 7 points, to show just how valuable he really is. We know the truth, and that's good enough for now, he will educate everyone else as the years roll on and he just keeps on winning.
