“Good guys” of the dead ball era?

[Eric72]

Connie Mack strikes me as the type of "good guy" you're looking for. Here's a Code of Conduct he created for his players:

I will always play the game to the best of my ability.
I will always play to win, but if I lose, I will not look for an excuse to detract from my opponent's victory.
I will never take an unfair advantage in order to win.
I will always abide by the rules of the game—on the diamond as well as in my daily life.
I will always conduct myself as a true sportsman—on and off the playing field.
I will always strive for the good of the entire team rather than for my own glory.
I will never gloat in victory or pity myself in defeat.
I will do my utmost to keep myself clean—physically, mentally, and morally.
I will always judge a teammate or an opponent as an individual and never on the basis of race or religion.
