Every year when a team wins the World Series, all of baseball goes looking for a trend that led to the success. Even if a team doesn't win it all, but makes it to the World Series, trends are searched for. This was the case last year with the Cleveland Indians, who lost in seven games to the Cubs, but still created conversation about their usage of impact relievers in key situations, rather than in traditional closer roles.
The Houston Astros won it all this year, beating the Los Angeles Dodgers and their massive payroll in the process.
