Case in point : In today's Netherlands vs Bulgaria game, the Dutch are favored to just win , by - 317 ( 5dimes) on the money line and if you wanna get them at -1/2, the odds are at - 339. You would think it has got to be the same. There's no extra time in group play or anything. It's almost never the same, but usually differs by a little, today is a bigger gap than normal.
