Winning the breakdown battle is one of the pillars of achieving success in modern rugby, whether it be slowing opposition ball or creating quick attacking ball.
And when the Springboks take on Argentina this weekend, veteran back-rower Francois Louw will go to the well for the 58th time to try and win that skirmish for SA.
The Rugby Championship clash in Durban should see a return for Louw, 33, to the starting line-up after he sat out the June series win over England.
The Boks battled through that series with captain Siya Kolisi at No6, a role he admits is always a challenge. Kolisi prefers to carry and defend close to the rucks, while Louw is more attuned to battling on the deck.
The pair are set to play in tandem this weekend, with Louw donning the No6 jersey, where he has spent most of his Test career, and Kolisi taking on the ball-carrying No7 role.
But the numbers on their backs will not alter their approach, as both players have particular strengths. Lions captain Warren Whiteley is likely to start at No8.
"Having played with Siya before, I know he can be immensely physical. We play quite a different sort of game," Louw said on Tuesday.
"I think he’s more of a ball carrier, but he’s also got pace and a big presence on defence. I’m more breakdown focused, and perhaps play a bit tighter.
"Warren is a fantastic player and offers a great lineout option. I guess you could say he’s a back trapped in a forward’s body. He links between the forwards and backs really well, he’s good in the outside channels and really gets all over the park. Warren has an immense work rate and pitches up every time to give an 80-minute performance."
Forwards coach Matt Proudfoot did not specify what number Louw would wear, but regardless, his job description will not alter much.
"Flo [Louw] was incredible on the end-of-year tour when he came in," Proudfoot said of 2017’s tour to Ireland, France and Wales. "A lot of people look at our No6 as just a fetcher, but he does so much work at the attacking breakdown to create quick ball, and interlinks well with the backs.
"What has always impressed me is his attention to detail and doing extra homework. He’s not just a strong, powerful forward, but he’s learnt the tricks of the trade when it comes to the breakdown. He’s brought a lot of knowledge into this team, and doesn’t want to just achieve for himself, but to improve the entire environment.
"It’s a vital combination to get right — you need to have the balance of physicality and the ability to go wide.
"Loose forwards have increased roles in the modern game — they have to run like backs and create width. The good thing is that we have guys with different skill sets who are quite versatile and can adapt. I’m looking forward to seeing how this combination performs."
Louw might only be available for the first half of the competition because of club commitments, but the influence he could have on the uncapped Marco van Staden will be huge.
Van Staden has been earmarked as the Boks’ next fetcher and he would benefit from the experienced Louw.
