How many World series have they played in in that time?? Also, how many LCS's have they even appeared in in those years. I know your a big "stats/analytical" guy so I'm assuming you can provide the answer to this?? In the past five seasons the Dodgers have been in 3 World Series, the Astros 2 WS and the Red Sox, Nationals & Rays have been in one WS each. If the baseline for being a serious contender is making the WS, then there are only five teams out of 30 that fit the criteria. I don't think the other 25 teams are just out here goofing around. As far as CS spots go you've got HOU (5), LAD (4), ATL (2), BOS (2), NYY (2), TBR (1), WAS (1), STL (1), CHC (1) and MIL (1). So only five teams with more WS appearances and only five teams with more CS appearances than the Brewers over the last five years.
