I am a little surprised that the Brewers are doing this well with the injuries they have had because they don't have the depth the Cards or Reds have. Over the course of the season I think it hurts them.
They don't have the Cardinals depth but they certainly have as much as the Reds outside of the bullpen. I don't think there is more than 3 or 4 games separating the top 3 spots in the NL Central. One team will do better in 1 run games and win like 91, another will end up around 88 and then one will be at like 85 and then the Pirates will hover around .500 and the Cubs will stink. Now if you think the Brewers are the 85 then I'm fine with that but that is still a line that allows for someone to pick them. They won 83 games last year in a down season where the bullpen blew 29 leads, with a couple better bullpen arms they would have been in the mix last year. I'm not sure Badenhop, Gonzalez and Gorzelanny count as better arms though. This isn't like someone picking the Cubs to take the division where they aren't discussion worthy.
They are a Peralta, Fiers, Burgos or Thornburg breakout away from having a good pitching staff. It is just hard to predict if one of those guys will actually take the step.
