There are at least two easy ways of answering the question of which are the all-time greatest teams: (1) the teams who were most dominant in particular seasons, and (2) the teams who have won the most World Series. The second criterion is easy, the New York Yankees have won by far more World Series than any other team in MLB history.
As for the first criterion, I have employed three easy, objective criteria to rank the top ten teams—those that were most dominant relative to the rest of their respective leagues in individual seasons. The three criteria are as follows:
- A winning percentage of .650 or higher. This means that for a 162-game season they won a minimum of 105 games; for a 154-game season, at least 100 games.
- They won the World Series (WS) that year. This criterion excludes several great teams that had phenomenal, league-dominating seasons; however, if a club fails to continue that dominance all the way to a championship, can I honestly rank them among the best-of-the-best all-time teams? I debated this at some length and decided I could not.
- Their Delta score ranking. (Their what score?) The first two criteria whittled down the possibilities tremendously. The teams meeting those minimum qualifications were then ranked according to a very simple statistic I devised: the Delta score. (It needed a name, right? Why not Delta (∆), the fourth letter of the Greek alphabet, which happens to be the first letter of the author’s name. (Disclaimer: I wrote originally wrote this long before the delta variant of COVID-19 had raised its ugly head.)
