I really don't see how you can bet against them right now.
Tonight vs Mets, the Braves have the better starter and better recent hitting/scoring. The only thing that seem equivalent on a stats sheet is their relief pitching and even that is a very slight edge towards the Braves.
Add that to the momentum factor and how leveraging this series is for the Braves.... They seem like the best play.
After this series, the Mets have the easiest schedule through the rest of the season (based on opponents W/L) so the Braves better catch them in the standings now.
