One fun thing about bubble football is that you don't have the typical football goal post you see on standard field games. Instead, there are goal posts known as "pens" or "tubs". This allows for a lot more strategic plays during the game. Because the goal posts are out of the way, the play that a team plans depends almost entirely on where the ball will end up after it is passed to the players. The only way for the ball to return to its starting position is to travel across the playing field. It takes a great deal of skill and strategy to be successful at this game. - https://www.holleyweb.com/
