He’s the son of a major-leaguer — and the godson of a joyous Hall-of-Famer, Willie Mays, none of whose ebullience has rubbed off on Bonds’s sullen personality.

Those testosterone like hormones ("steroids") can have some pretty impressive effects on one's personality.

Bonds was a jerk when he was a skinny young outfielder in Pittsburgh, before the 'roids. He comes by that naturally.

Yes steroids can affect personality, but in Barry's case the "sullen" attitude is the result of being a member of an opressed minority.Some of the statements attributed to this prima donna show outright contempt for the fans, and our society in general. Willie Mays, Hank Arron, those days are gone. Baseball is all about $$$$, and doing (taking) whatever it takes to make it to the top. Kinda like the prevailing attitude of our culture.
