UNDERSTANDING why a team succeeds is Ben Darwin's business these days. 

The former Wallabies rugby representative is the co-founder of Gain Line Analytics, which has scoured the world's sporting competitions to figure out why some teams win and others don't.

What they've found is that clubs are not placing enough importance on the understanding between athletes, their roles and the system they play in. 

Darwin joins AFL.com.au podcast Trends this week to discuss his philosophies on sporting success.
