20 in a row is pretty fucking impressive. It takes a great team and a little luck. The 2002 Moneyball A's went on to win an incredible 103 games. When I went to look up exactly how many games they won I forgot how impressive their early 2000's run was:
That's eight straight years with at least 87 wins. Had they won a World Series or two Billy Beane would be looked upon much more favorably. I'm a huge Beane supporter but even I have to admit it's a little odd that none of these teams ever even made it to the World Series. A lot of people argue that the MLB playoffs are a different game and didn't suit what the A's did well during this time (not stealing bases, working pitch counts, drawing walks). After watching the Royals do the exact opposite the past two years (aggressive base running, swinging at first pitches) and get to two World Series I am starting to agree. Regardless I'm not sure we will see 20 in a row again anytime soon.
