This is a great move for Messi.
This might just be the gig that makes him more famous and popular worldwide than Ronaldo.
Let's not forget, American media is the most powerful itw. The soft power, pop culture influence and reach they possess is miles above any other nation on the globe.
This Hollywood and NBA association will give Messi even more limelight and popularity.
All he has to do now is learn a bit of English and go on some talk shows. He'll be known by all circles in the States.
These last 2 years have done a lot for penetrating his brand into territories unknown. The World Cup, the narratives around him and the MLS move all makes so much sense for his brand.
