I don't know, it some places maybe but look at how far football has come in America. A random Thursday night game is going to beat out a World Series/NHL NBA Finals game. It really is our most popular sport.
Would I encourage young people to do it, not with that concussion bullshit, you don't want that CTE stuff that's game over. I could see more day games like you said motorhead and more padded helmets though.
