If at some point on Saturday the tide has turned against Wales, the French are flooding through in attack and causing chaos it will be the old men of the sea who guide those in red to calmer waters.
The two recent Tests between Wales and France have been mad, edge-of-the-seat thrillers. Both have been won by wily Wales when all looked lost.
Last year they were 16-0 down at half-time in Paris, then in the quarter-final of the World Cup in Japan Les Bleus led 12-0; in both Welsh waves eventually swept France - who suffered extraordinary head-explosions - aside.
Wales are to name the most experienced Six Nations team ever to get the better of France
Wales captain Alun Wyn Jones is a key part of the old guard and he can guide this side to a win
Those are the only two matches Josh Adams has played against France, and he explained how his senior men can be a steady hand on the tiller amid a storm.
'We have got some great leaders,' said the winger who is fit again having limped off in the Ireland defeat. 'Alun Wyn Jones is fantastic and does really steer us through some tough times on the field with his leadership.
'Biggsy (Dan Biggar) at 10 is another fantastic leader, he really gets the backline going, a fantastic game manager, he understands the game really well. I could reel off Tips (Justin Tipuric), Toby (Taulupe Faletau), Ken (Owens), Halfers (Leigh Halfpenny) at full-back, even George (North) on the wing.
'These boys have got so many caps under their belt, they have played at the highest level, in the biggest matches you can possibly get, Lions deciders and things.
'On some occasions experience like that does help you, a calm head in moments of madness when you are up against it.
'If the game goes down to the wire, the experience on our side will help but that doesn't necessarily mean it's going to win us it.' Perhaps more than most other Test teams Wales - at least under Warren Gatland - were masters at clinging on to games.
On Saturday, Wayne Pivac fields the most experienced Six Nations team ever, with 859 caps. Only 14 other XVs in the history of the game - 10 of which have been All Black sides - have had more Test appearances in them.
