6. Brad Thorn
With forearms the size of a Christmas ham, Thorn couldn't help but terrify people. Any hint of trouble and Thorn would be on the scene before anyone could count to two. He arrived, trouble stopped - it was always that simple.
5. Keith Murdoch
Even Pinetree Meads was wary around Murdoch - that's what happens when a man allegedly pulls his car up Dunedin's steepest street...with his teeth.
4. Michael Jones
Those who ran into Michael Jones knew they had just met irresistible force. Quiet and God-fearing, he was a new breed of destroyer, inflicting his damage exclusively legally.
3. Richie McCaw
He played throughout the World Cup on a broken foot and has been subjected to a legion of cheap shots in his 116 test career and taken them all without retaliation. McCaw is a genuine hard man: an old school hard man, even.
2. Colin Meads
It wasn't just playing with the broken arm that made Meads a legendary enforcer. He had an aura - he emanated a definite vibe that suggested he should be approached with caution.
1. Buck Shelford
Shelford changed everyone's thinking about what being tough actually meant. The fact he was able to play on with badly ripped testicles says it all.
