I might be nuts, but I think costa rica has a shot at an upset here. I think they've put in couple new plays to breakdown Netherlands defense and maybe get a 1st half score. The let their D carry them trough the rest of the game. Might not happen, but I like the +658.
Yes they have a chance, and the oddsmakers have given you pretty much the value for the risk for that chance. IMO it really depends on Netherlands fing up.
I am throwing $40 on costa rica if for some reason they go ahead 1-0 in some kind of miracle or own goal I am cashing out and taking some profit if I can.
