Pitchers never do. Baseball nicknames go on forever, because we feel we know so many players intimately. Football monikers run out fast. We just don't know that many of them as people. Baseball measures a gift for dailiness.
Football has two weeks of hype before the Super Bowl.
Baseball takes about two days off before the World Series. Football, because of its self-importance, minimizes a sense of humor. Baseball cultivates one. Knowing you'll lose at least sixty games every season makes self-depreciation a survival tool. I may want to do that myself later.
