On a night when Ireland demolished the Springboks in a record rout, Iain Henderson announced himself as the home side's new enforcer.
All the great rugby teams have a teak-tough lock in their engine room, an uncompromising character who sets the tone with his physicality and presence.
The sight of the Ulster lock trampling over South Africa's stand-out second-rower, Eben Etzebeth, was one of the highlights of a stunning Irish display.
'Hendy's a special player, I've known him and played alongside him for a good few years now, and he's just a special player,' said Devin Toner. 'He's a monster in the gym and a monster on the pitch.
'He's turned into the enforcer. It's amazing, especially when you have someone who is a talisman like Etzebeth — he's their captain, he's renowned for being the physical man on the pitch.
Ireland recorded their biggest victory over South Africa thanks to a ruthless display masterminded by the half-back pairing of Conor Murray and Johnny Sexton.
Three Sexton penalties and a first Test try from wing Andrew Conway had the home side 14-0 up at the break. A penalty from Boks fly-half Elton Jantjies was all the visitors could muster in the second half.
Rhys Ruddock, Rob Herring and Jacob Stockdale crossed in the last 10 minutes as Ireland finished with a flourish.
