win a WS ring, no doubt.
there are a lot of things you can't control to be part of a world series champion, you can hit a home run a game, but if you pitching sucks, you won't win the championship. because you can't, most of the times, control the destiny of your team all by yourself, it makes winning a WS ring that much harder and that much more enjoyable. not to mention that you will be able to celebrate the win with all the guys who helped each other for a whole year, whereas if you break the home run record, they will be happy for you, but won't buy you dinner.
i personally think what bonds really wants is to pass babe ruth, he doesn't really care about aaron.
