I only bet on soccer myself. Oh, I place a small wager on the superbowl every year. I've won 3 years running but when I say a small wager, I mean, a very small wager so it's not much but hey, $ is $.
The small advantage of American Football is the DRAW, if the unlikely outcome of the draw occurs, the wager is refunded. However, in soccer, you either pick Team A, B or the Draw. Now, I don't care how you look at it, that is a disadvantage right there, pick between two outcomes or three?
Pinnacle has reasonable limits at open unlike CBB totals. Can make a decent sized bet early and usually get a good number. Great sport to watch because it is not jammed with a ton of commercials. Also you can watch all the games online in HD at the MLS site for just $29 for a seasons worth of games.
