The 23-year-old has fought his way into the Wales starting line-up of late and clearly has a head for heights after previously working high up at Margam steelworks before his rugby career took off.
His work under the high ball has been extremely impressive as the aerial battle becomes increasingly vital in international rugby and Williams will return to the GUINNESS PRO12 keen to carry on his momentum.
The Welsh region are currently in a battle for a top six finish and with comparisons to JPR ringing in his ears, Williams admits life could not be much better at the moment.
"I've had tweets from people saying I'm like JPR. That's overwhelming because he's a Wales legend," he told Wales Online.
"I just give 100 per cent. If that means I help the team then I'm happy to do so.
"If I happen to get hurt, so be it. It's not something that bothers me.
"I love jumping for the ball. It's an important part of the game and we have to make sure we do well there. We have been working on winning the aerial battle."
