Former Cowboys coach Tom Landry talks about character in his book called "The Landry Legend."
Coach Landry talks about what he looked for in players as his teams improved:
"When I first started coaching I thought mostly of physical ability; quickness, agility, control, strength, and explosiveness."
Then, as we developed into a stronger team, character became more important. The character and competitiveness of a player become the more controlling factors."
"When you reach a championship level, what separates you is basically the character on your team. If you have enough character, it'll usually pull you out of tough situations."
