When is a Team not a Team?

Perhaps it's not a surprise, but at parties i often get into conversations about sport. Last night i was asked this philosophical question, while discussing the departures of Ben Hannant (pictured) and Friday night's 4-try hero Denan Kemp, from the Brisbane Broncos at the end of this season.


Technically it was about how many players have to leave before it's no longer the same team? The best i could explain was that it is similar to an extended family, where new people are born (or married) into the clan, while others pass on. Over time, the composition changes but it's still the family.
