I watched John O'Sullivan's TedTalk last year, when doing research on athlete drop-out rates in sports. His work is excellent.
Please take a look at his article below - not because it talks about the All Blacks, but because it talks about the culture of TEAM and of being a better team-mate in order to make the team better.
I believe we have some very good team chemistry, and I know we are getting better; why not be the best?
