Great profile by Michael Lewis of Mike Leach, Texas Tech's football coach. Leach "believes that both failure and success slow players down, unless they will themselves not to slow down." 'When they fail, they become frustrated. When they have success, they want to become the thinking-man's football team.'" Must-read article if you're even a casual football fan. Here's another article on Leach from the SJ Merc.
Update: Steven Levitt and the Freakonomist commenters weigh in on Lewis' article. (thx, michael)
