John L. Sullivan “wrote” his life story for The Boston American in 1905. The former heavyweight champion had always been a baseball fan, played some semi-pro ball, and was once arrested for participating in a Sunday game.

John L. Sullivan
In the 1905 article, he talked about the evolution of personal responsibility of the ballplayer:
“What with firing away his money and having fun with (Cap) Anson, King Kelly had a merry life, but a short one. He was a king among ballplayers and a prince among spendthrifts. Once he lectured me on the wisdom of getting the savings bank habit.
‘”You’ll need it someday, John L.’ he said.
“’How about yourself going broke, Mike,’ I asked.
‘Not me. When I need money, I can take my turnout and go selling milk,’ he replied.
“The turnout he referred to was the horse and buggy given to him before a ballgame on the National League grounds in Boston. The rig was a present to the king by his subjects in my town.
Mike “King” Kelly
“When King Kelly passed out, the future emperor, Napoleon Lajoie was driving an ice cart in Woonsocket. Prosperity almost carried the Frenchman off his feet, but the lesson of Mike Kelly and some more of us foolish ones was drilled into him. He cut out the red-eye and got a bank book, and today he is the king of them all and getting rich. He doesn’t intend to get off the water wagon and go back to the ice cart. The difference between King Kelly and Emperor Lajoie is the difference between the old style and the new in all kinds of sport, and the stayer is the man behind the pledge.
Napoleon Lajoie
“Kelly died early. Lajoie grows better every year, and if he were to take up boxing, he could sprint faster than (Jim) Corbett, punch as hard as myself, get away as quick as Fitz (Bob Fitzsimmons), and handle his fists like Tommy Ryan. Moreover, his hat fits. I call the attention of all the temperance lecturers to Larry Lajoie as one of the best examples they can use in their business.”
