I think decades is a stretch. It's grown massively in the past 5 years, let alone the past 10. More coverage will result in a larger fanbase...soon. Now is a brilliant time to get in on the ground floor. Because I don't think it's if soccer takes off in America...more and more it's when. And I think there are a lot of very rich and very influential people that realize that too. Especially considering the fanbase tends towards the much sought after younger demographic.

Yeah, TV money over here is going to be divided equally. Could be a good market for merch after the KitBag stuff runs its course. Other than that, no, I don't think there is a terrible amount of money to be made over here. Not saying it isn't worth it, but it's not the solution to Everton's financial woes.
Short of perhaps a partner club, kind of like how NYCFC is except more of cooperation among equals and not outright ownership with FC Dallas or Sporting KC, whoever ends up putting in this hypothetical bid from Kansas. Then you could have two academies working towards the same goals and covering a lot more ground.
