This is the best explanation of Sabermetrics I've ever seen:
The definition of "contending" is based on a complicated formula that I've used for years:
[(BT) + .(3 * sV) + (.03 * ab)] * 6 or 7, idk
In which "BT" stands for Buffalo Trace, "sV" is sweet vermouth, "ab" is bitters, and "idk" is an unknown variable. This formula is a key pillar of what's known as "sabermetrics."
It comes from this article: http://www.sbnation.com/mlb/2015/1/14/7546735/baseball-predictions-math-hella-graphs, "in which we look for the teams that are built to win now, the teams that are built to win later, the teams that are built for both, and the Phillies."
