  • Growing field

    In his new book, Sports Analytics: A Guide for Coaches, Managers, and Other Decision Makers, Benjamin Alamar says that sports analytics is in its infancy and teams can gain a significant advantage by using it. He cites a recent survey which showed that while 37 percent of teams have easy access to one another's data, 37 percent of them do not employ a database programmer.

    Alamar says that sports and business need analytic tools and computer power to sift through massive amounts of data to produce reports that can be used to develop a competitive edge. He refers to how small market teams such as the Oakland A's have used sports analytics to successfully compete with the larger, better financed organizations.

  • How to bet on sports and win big

    Chad Millman, Editor in Chief of ESPN The Magazine, tells how sports analyst Mike Wahl has examined sports betting from many angles and found an almost sure winner in college football. Typical of many current sports gurus, Wahl earned an MBA and then worked in business as a financial analyst before switching to sports.

    To find the right winning bet, Wahl searched through six years of college football games (376) when a team was favored by 20-25 points. To bet on an outright game winner is supposed to be evened out by having the wager on the favorite cost more than the one on the underdog. He found that if you bet the same amount on the favorite as an outright winner, you'd have won overall for six years in a row and your return would have been 12.24 percent. But I'm sure this loophole will be closed very soon.

  • WAR

    Billy Beane changed the face of baseball by using new statistics, such as on-base percentage and slugging average, as a better indication of a player's vaue than traditional baseball measurements — batting average, stolen bases, and RBI. An even newer analysis of a baseball player's value is called WAR (wins above replacement) which attempts to indicate how much a player contributes to his team. One major leaguer who stands out is Atlanta Braves outfielder Jason Heyward. His three-year WAR rating is the sixth highest for outfielders under 22 since 1961.
