In 1986, Maradona wore a shirt that read "No Drugs" and Platini "No Corruption"...
Years later Maradona overdosed and Platini was arrested for corruption.
What about Pele?
Well, Pelé wasn't wearing a T-shirt with a message, but at the end of his professional career he said that the world should take better care of children...
A few years later he did not recognize his legitimate daughter.
