Actually, I started my ring career as a terrific hitter; then my hands cracked up and I had to resort to boxing and tricks to win.
My own ambition in the ring had always been skillful boxing, speed and defense - on the order of Mike Gibbons.
No matter how skilled a boxer may be, he cannot stand up in the ring and give a good account of himself unless he is in perfect physical condition.
But in the ring Jack Dempsey was an instinctive fighter. I doubt if he ever planned anything in the ring, or thought about it much.
To stay relaxed and avoid tiring mentally and physically, it is necessary to get plenty of sleep and frequent rests during the day.
Being in top shape can make you a winner, while entering the ring in poor shape, not only cuts your chances of winning, but can be very dangerous.
