As much as we poop on the Brewers, it isn't like they are leading the division and that is the only reason they would be in the postseason otherwise. We would be the #2 WC right now just behind the D Backs. The Twins, on the other hand, wouldn't be in a WC spot if they weren't the divisional leader.
The NL Central features 3 positive run differential teams and nearly a 4th with the Brewers. The west features two teams and the Braves are the only team in the east with a positive run differential. The NL is just that terrible so far...it is the Braves/Dodgers and then a bunch of .500 type teams.
Now, that will likely change. A few teams will probably put things together....but for now, we are kind of playing as 'blah' as the rest of the league.
