A story about Paul "Bear" Bryant, the late coach of the University of Alabama's football team, demonstrates his belief in relentless attention to detail.
One day during a practice, a visitor observed Coach Bryant doing something that aroused his curiosity. From time to time during practice, the coach would reach into his pocket, pull out a crumpled little piece of paper, read it, and then put it back in his pocket.
The visitor watched him do this several times during practice, and then finally mustered up the courage to ask the coach what was written on the paper.
Coach Bryant simply smiled, pulled out the paper, and let the visitor read it himself.
"It's the itty bitty, teeny tiny things that get you beat."
