What it would need : An enormous financial crisis in Europe. MLS teams being allowed to take part in Champions League and Europa League. Baseball or Football having a radical decline in popularity. An intelligent and serious leadership in MLS. I don't see any of it happening. So no no chance at all. But MLS should be better and more serious than it is at the moment, I see it regressing in many ways which shouldn't be happening. That being said from what I know soccer is the most popular sport in North America in terms of people actually playing it for real. It is in Canada since around 1998. I think it's the same in the US. For me that means much more. I prefer people playing the game they love than "tv fans". For me that's the real thing. Those people sure deserve a better product and more serious one than mls is now.
