Dome Team = Offensive Team

No, I'm giving you a clear example of opposite evidence, that you happen not to like.

The goal posts are all in their original position. Fast turf assists multiple parts of the game. It doesn't evidentially in isolation make a team 'better' in one particular phase, as much as you want it to.
Furthermore, even if it did, you still have to play 47-52% of your regular season games away in a location where this 'natural advantage' has zero bearing. Guess what wins in less than ideal field conditions more often than not? I'll give you a hint, it's not a large reliance on the passing game....
I don’t need evidence because there’s nothing to argue. It is a fact that the Saints play indoors. It is a fact that every stadium provides certain advantages. It is a fact that it’s easier to throw the ball accurately inside due to the lack of elements.

It is also a fact that the Falcons play indoors. That means a MINIMUM of 9 out of 17 games a season will be played inside. That means 100% of your regular seasons will play the majority of your games indoors.

You can say that it is an opinion that you should design your team with consideration of your natural advantages. You would be wrong but you (especially you) certainly deserve to have that wrong opinion.
