As a prop Fanie's lack of height was probably his greatest asset, because the shorter the limbs of a player, the less the margin for error. Just look at Michael Chang, who won the French Open Tennis Championship in 1989.
Fanie was a prop who could hold his own against exceptional opponents. He, Abie Malan, and Piet du Toit formed a front row second to none in our rugby history.
Over and above that he was able to cover the field at an exceptional pace and was always a great asset to South African rugby.
