Research on "elite" Teams and pretenders

I think that at this point it is to early to tell just on SOV and SOS. Teams are still coming together. The Saints started off ready to go on Offense but the Defense is getting better. Yea it says something but its not the whole story. BAL looked unstoppable after 3 games.Now not so much. NE is looking up and down but who knows what we get at the end of the season. I think it will take a few more weeks before this is meaningful. Teams have bad games and good games. Thats why they play the whole season.
That being said. I think IND, Giants and Den have some weaknesses that can be exposed by a well coached team. Saints look solid on both sides. MIN looks solid.
