Military leaders aren't made. They are born. To be a good leader, you have to have something in your character to cause people to follow you.

I think as far as any kind of pressure on a football team or on an individual in professional sports really depends not only on that individual but the leadership they have on the team and the leadership they have on the coaching staff. A lot of times, they can divert some of those pressures off of the individual and off of the team.

An objective truth and individual reason are feared above all.

But I was always a bit of a gypsy, anyway. I spent five years at Oklahoma State, five years at Miami and moved on after winning the national championship, and five years with the Cowboys. So, I was ready to move on. We won back-to-back Super Bowls, and I felt that I accomplished what I wanted to accomplish.

I tend to personally judge issue by issue rather than sort of endorsing this football-team mentality that we fall into in this country, where it's all about the team.

Of course the Premier League is the most difficult league in the world because it's so even. I think you can't really compare other leagues with the Premier League. In the Premier League, every team can beat every team, and in football, that's something where you can have surprises.

My mom was a great tennis player, and I remember being six or seven years old watching Steffi Graf and Monica Seles in Wimbledon in my house. I've always been a tennis fan.

On the tennis court, one needs a cool temperament, tremendous ball sense, reflexes, speed, hand-eye co-ordination, power, timing and peak physical fitness. Off the court, the player and support team need skills in planning, execution, travel, an ability to raise funds when needed, and several other talents.
