Scarlets tighthead prop Samson Lee has been marked out as the successor to current Wales and Lions star Adam Jones.
Lee was a rare positive for the Scarlets after their thrashing against Leinster in the opening weekend of the RaboDirect Pro12.
Currently uncapped, the 21-year-old has been talked up by Scarlets forwards coach Danny Wilson, as he adapts to the new scrummaging laws.
"Samson is one for the future," Wilson told WalesOnline.
"The new scrums really suit Samson, his shape, the way he scrummages he can hopefully use to his advantage.
"Samson is a squat tight-head - he's already down there. And he's very barrel-chested. You're going to see a lot of loose-heads having the upper hand and the dominance.
"It's going to be how tight-heads deal with it. I think Samson has already shown he can.
"You can train hard in the gym and learn how to play rugby in an academy but, as a prop, there's no substitute for game-time."
Wilson was also pleased with the Scarlets' set-piece work against the champions, underlining the effects the new laws will have on scrums moving forward.
"I'm really pleased with the scrum and line-out at the Scarlets, we only had four scrummage feeds last weekend," added Wilson.
"When you are dominating you want as many as you can get because they usually end in positive outcomes or a penalty.
"Hopefully an attacking loose-heads like Phil John will do some damage for us.
"The scrum is now a far more technical aspect. Tests they did at Bath University showed it took 25 per cent of the hit away, so now you have got to be able to scrummage after it."
