Yup, until they work out a camera system that can cover every part of the field at the same time, then edit it so that it makes sense, you are never going to be able to follow the action. Main problem is 14 people, all capable of making or breaking a game...... every other sport has a point of focus, either a ball, puck or goal or it's a one on one. Anyone think of anything like paintball that gets any coverage?
So, problem is, to get it mainstream it needs proper coverage. To get proper coverage it will cost a fortune. To make the money to cover it properly, you'd need mainstream advertising. Catch 22.
