Think about it, all the turnover the Braves have had, and they haven't had one off year for 14 years. And there were years they literally needed to win 100 games just to win the division and make the playoffs, not like San Diego that probably will get in with a losing record. The Braves were picked to do squat this year with so many rookies, and yet here they are celebrating another pennant.
To have a streak that long is a testament to the management of the whole organization. But there's also an element of good fortune as the divisions were expanded several years ago.
