In 2016, the South African Springboks played 12 Tests, winning 4 and losing 8, representing the team’s worst professional-era season. They finished 2016 ranked 6th in the world before slipping to 7th in the 2017–2018 World Rugby rankings. Over the next 10 years, they played 116 Tests, won 77, lost 36, and drew 3. That’s a 66.4% win rate. Along the way, they won the 2019 and 2023 World Cups, dominating the international team rankings. Probably the most impressive statistic is an 85% win rate across 2024 and 2025.
A more interesting set of statistics is the number of players who have played for the Springboks over this period. While the stats vary (and for explainable reasons), over 120 players have worn the jersey, with approximately 88 being debutants. Players arrived, retired, coaches changed, and yet something recognizably "Springbok" persisted.
The obvious question is how the Springboks became, and have remained, so dominant. The more interesting question is how, despite their constituent parts continually changing, their behavioral spine has been replicated and sustained over the 10-year period?
Much has been written about Rassie Erasmus (Head Coach), the quality of the players, the Bomb Squad, the novel and experimental tactics, the team culture, a national purpose, the team’s diversity, etc. Significantly less has been written about how this team has been able to bend and mold players into a performatively persistent, behaviorally stable, and identity-consistent collective. The Springbok team has a way of playing, but they have a more distinct and harder-to-understand way of being. In the way that players make teams, this is a story of how teams make or shape players.
The Springbok team has behavioral gravity. I distinguish this from chemistry or culture. I see culture as partly constructed and partly emergent. Culture initially specifies expectations, norms, and values, as well as names and attributes behavior that models it. Culture is guardrails. It specifies, “This is how we do things around here.” Culture is what the team says it is and values. Gravity is what the team does. It’s the behavioral pattern the players experience. Gravity is what makes some ways of being increasingly likely to persist. It is the invisible mechanism through which accumulated interactions keep recreating the conditions for particular patterns of behavior to continue or be more likely. It’s dynamic and enacted.
Behavioral gravity is the accumulated memory of thousands of interactions acting on the present. Gravity does not specify; it biases. It pulls players, their behaviors, and expectations into alignment without being told how. There is no gravity manual. It’s the residual effect of every prior action that creates the conditions for the next set of generative actions. It’s both a condition creator and an enabler. No one entering its orbit goes untouched. Players are, in turn, shaped by the team while also shaping it. It’s how the team outlives the players who pass through it. Culture and gravity continually reinforce one another. Culture names and gives meaning to the patterns; repeated enactment gives those patterns gravity.
Gravity emerges through connection, relationship, interaction, and shared experience. Kept promises, accepted roles, hard conversations, how selection is explained, how mistakes are treated, how senior players respond to competition, how the group behaves when things begin to go wrong. Each interaction leaves a small residue. Each quietly smuggles some of the conditions for the next interaction forward. Eventually, the team begins pulling its members toward particular behaviors. Not perfectly, but probabilistically: honesty, trust, effort, humility, and grit become more likely to keep emerging. Gravity is how teams forge players.
Gravity gives action meaning. Starting on the bench can easily feel like a reduction in status. The “Bomb Squad” (second-half replacements) became central to its approach. The bench role did not change; its meaning did. A player entering that role is pulled to occupy it as a Springbok occupies it, not as a demoted starter. They aren't waiting for the real players to tire. They're trusted to finish the job. The young player who comes next watches how the role is worn and takes it up the same way.
Importantly, gravity’s process is neutral. Its effects are as easily generative as degenerative. A team is always being rewritten by its own micro-interactions. The state they enable either encourages trust, communication, intelligibility, etc., or creates conditions for their erosion.
Gravity is invisible, but it is not unreadable. It leaves traces in how players experience the team, in what they notice, trust, expect, and withhold. Those traces can be surfaced, and once you can see the pull, you can begin to shape it.
Core takeouts:
1. Teams persist despite player turnover.
2. Teams shape players as much as players shape teams.
3. Accumulated interactions create a behavioral gravity.
4. That gravity changes what future behavior becomes likely and what actions mean.
5. Gravity can be generative or degenerative and although invisible, it leaves observable traces.
Circle-In gets teams to perform closer to their potential by providing coaches and players with the behavioral intelligence needed to build more cohesive, self-aware, and smarter teams.
