LOL OK. When you said "The NFL is rigged. They did what they could to have the 2 biggest audiences meet in the superbowl" I assumed by "they" you meant the NFL themselves, but whatever.
Do I believe the game is above corruption, that decision makers don't let money take precedence over what is right? Of course not - this is a league where Colin Kaepernick can't even get a tryout but Mark Sanchez still gets trotted out to start games, and where Eric Reid mysteriously gets drug tested every 13 seconds.
What I don't believe, however, is that anyone needs to rig who makes it the Superbowl in order to make money off the game because it's the Superbowl. And again, I come back to my previous point: even if someone did want to rig this for the reasons you suggest, and they somehow had the power to do it, they would've rigged it for the Cowboys who have a way bigger fanbase than the Rams.
