I grew up outside of Boston and was a big Red Sox fan as a kid. My father used to talk about two baseball players, Billy Martin and Jimmy Piersall. He said Piersall was the greatest outfielder he ever saw, and Martin was the toughest ball player he ever saw. My father was old enough to have seen games at Braves field as a member of the knothole gang and used to sneak into Fenway. He saw Ruth Gerhig, Dimaggio, and Williams, and yet he talked about those two.
No one made Mantle drink. If anything, Martin would have protected Mantle. I've heard that story many times. And for what its worth, Mantle did more for organ donors than any human being. If they didn't move him up the list, they should have.
