It is a good bet IMO. Should the Cubs and Dempster win? Absolutely. Should they be the -300 favs they will be? Not a chance. In baseball there probably isn't a team that should be -300, and going against that team every time will always be a good bet. Would I personally bet that? No, because I'm not a value better. I bet on teams I think will win the game. But yes I would say it is a smart bet to take the Nats, especially tomorrow when people are thinking there is no way the Nats win three in a row, two against the Cubbies.
