Vegas and Fifa co-worked on this world cup and they will succeed. FIFA's role : "we will give you a ball that will be a nightmare for the goalkeepers and a dream come true for the strikers".
Vegas invited bettors to take the over 180 goals fot he whole competition : 58 games, 180 goals under the given conditions of the magical ball, with countries rarely catching the World Cup, or first timers (new zeeland, north korea, honduras etc). A huge amount of money is on that over, as well as on most of the matches. And, so far, we have had 14 matches, and 2 overs (cuz brazil was initially at 3, then went to 4.25 if Im right). The situation won;t change, the bookies will drop the lines for totals in the next games, many will be under 1.5, 1.75, will eventually get burried by a 2 goals match, but overall, it is gonna be a very low scoring World Cup.
