Maybe you are right, but I'm curious what evidence you have that it is easier to throw the ball indoors than outdoors? I get that it seems like it would be that way, but lots of times those impressions turn out to be wrong when we look at numbers. And there are plenty of great passing teams that played outdoors, i.e. 80s and 90s San Francisco, 70s and 80s Chargers, 80s Dolphins, and 2000s Patriots. I'm sure there are more that I am not thinking of, but the common denominator seems to be having a great QB, not where you play.
So, I think your team should take on the identity of the players you have. If you have a great QB, throw the ball. If you have a great RB, run the ball, etc.
