Another example would be Mickey Mantle.
He'd be hungover, or even drunk when he played, but he'd go out and sock three homers.
NOBODY really cared what he did off the field.
Imagine what Babe Ruth could have done if only he’d cut down on the smoking, the drinking and the sex....especially between the innings.
I agree, until that partying starts impacting performance If Manziel had thrown for 6000 yards of passing, we wouldn't be having this conversation.
Namath, Merideth, Stabler, etc. were probably just as bad, but they delivered.
