The Dodgers (25%/20%), Astros (17%/20%) & Yankees (16%/15%) are the only teams with realistic chances to win the WS according to 538/FanGraphs. According to BRef it's only the Dodgers (31%) & Astros (15%) with a realistic chance to win the WS. I guess for me a "major failure" would be something like what the Nationals are doing. Spend a bunch of money, aim to compete, fall on your face. What the Brewers are doing now, competing for the division/postseason, is exactly in line with expectations. Coming into the season they were not considered WS favorites & no realistic combination of moves could have made them one.
