What position groups are better than our Super Bowl year or 2011

People need to stop taking away from how good the 09 defense was. The whole point of defense is to take the ball away and we were top 5 or even better and we also were great on 3rd down and redzone defensively. I don't care how many yards they gave up, yards are close to meaningless defensively.
The whole point of defense is to stop the other team from scoring- turnovers are obviously part of that but certainly not THE point
There is obviously some skill involved in generating turnovers - ripping and punching the ball, breaking on a route bc you’ve studied tape
But there’s way too much luck involved to bank on turnovers as a core strategy
(knowing where Manning is likely to throw on a route is skill/smarts - being in right place/right time when Favre has a brain fart is luck)
