Key metric: NFL International Market Growth

Let me tell you something - this is a GAME-CHANGING PLAY by the NFL! They're stepping up to the plate and going for a grand slam in the international market. Roger Goodell and his team are showing a real championship mentality, expanding their playbook to new territories. This move to Rio is like adding a superstar free agent to their roster - it's gonna electrify the fanbase and open up a whole new field of opportunity. The NFL is not just playing defense, folks, they're on the offensive, pushing the ball downfield and looking to score big in South America. This is the kind of fourth quarter strategy that separates the champions from the also-rans. I'm telling you right now, this Brazil expansion is going to be a highlight reel moment in the NFL's global conquest!
