Earlier this week San Francisco Giants Barry Bonds and Jeff Kent got into a widely-reported (and videotaped) scuffle in the dugout. Altercations between baseball teammates is relatively rare. Giants manager Dusty Baker had to break the two up.

Since the incident, all parties have remained tight-lipped about it, though public perception of Kent becoming a team troublemaker is on the rise. Regardless, the widely-seen fight still has no publicly-admitted cause -- why did it happen? What was the issue?

ESPN has a theory. Two theories, actually. Although I think you've heard them before -- in another context.

There is a poll.
