Former Cowboys great Cliff Harris wraps up ESPN Dallas' Old School 101 series in which former players take a look at the problem areas of the current team and give their opinions and discuss the current players at those positions.
Harris, a six-time Pro Bowler who has two Super Bowl rings and picked off six passes in 21 playoff games, says he took an analytical approach to playing safety based on his math background.
"I played percentages," Harris told ESPNDallas.com's Calvin Watkins. "You look at all the data that is involved and you narrow it down to what can possibly happen to those percentages, and then you can break it down to what this team did during those percentages. Then you narrow it down to that moment in the space and time when you're playing a team."
