Frazier was not a big man at all. Frazier was about 5'9, but he would make anyone run. Put up your dukes and cover up because he's coming. He never backed up from anyone.

Growing up poor, I didn't even have a lunch to take to school. Lunch was 26 cents, and we didn't even know what 26 cents looked like. I didn't love school because I wanted to disguise that I was poorer than everybody else.

In 1973 I became heavyweight champion of the world with 38 victories, no defeats as a professional. You get to a point where you think you cannot lose. I felt like I had the greatest power with my fists, I was the strongest man in the world.

Iron' Mike Tyson is the last boxer who was truly embraced by the media. They followed him around. You didn't know what he was going to do next: bite you, cut you, fight you. When you think about it, that defines him - it was an exciting adventure.

Football is full of different characters but there are perhaps none who have a split personality quite like Jose Mourinho, as I can testify from personal experience.

Throughout my career, I was never able to relax; I always had to go on the field with another responsibility. I felt like I was playing, not just for my team, but for my race.

My wife hates football, and my kids don't really care.

I've been very fortunate and blessed to have been able to play football at LSU.
