LOL. There is a pretty big difference between producing professionals to the NBA and producing professionals to MLS.
You like college soccer - good for you. Understand there is a reason 99.9% of the population doesn't even know it exists.
A sports popularity has nothing to do with its level of play. If a college sport is producing professionals at a constant rate, its level of play must be pretty good.
Whether anybody cares or not doesn't matter.
