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

It would be an interesting discussion and maybe help shed some light on the state of the team. I think we are as talented on paper as we have ever been so what is missing, what is causing us to not reach our potential. It’s easy to say it’s Brees because he was better than Winston but it has to be more than that. There are a lot of above average QBs that are winning with less. So maybe we breakdown position groups and coaches and see if there is an interesting conclusion?

We know it’s QB for sure so that’s done and not really up for debate but let’s start with the O line.
Which group of the 3 is more talented on paper then on The field?
In 09 and 11 we looked like the best team in the league the vast majority of the season.

Though it’s early the eye test we look like a 7 win barely top 20 team.
