WHY GOLIATH WAS AN UNDERDOG. Here is a TED talk by Malcolm Gladwell at the TEDtalks site in which Gladwell explains that David should have been a heavy favorite in his encounter with Goliath—Goliath brought a knife to a gun fight. Gladwell compares the speed of a stone from a sling to a major league fastball.
Notice what a wonderful story teller Gladwell is in his quiet uninflected way.
