Cullen and Shane... but able to scale the heights
spell. After initially struggling for game-time his form improved under Pat Lam last season as he helped them win promotion back to the English Premiership.
Now he is back in Wales he admits his Scarlets departure was probably what was needed.
“I probably hit a brick wall and had to start again,” he says.
“Things didn’t work out, I didn’t play and had to go and play semipro.
“I ended up doing a year with Wales sevens, and it was really beneficial to go away and concentrate on some aspects of the game.
“I enjoyed that time but then had the offer to go to Bristol and restart in terms of my rugby.
“When you’re not picked and have to go and play elsewhere, it is frustrating. But going to Bristol was a fresh start and out of the goldfish bowl.
“It was a frustrating three years before last season, which was good for me and I learnt a lot under Pat Lam (Bristol coach). I developed a lot of my game from being able to play week in, week out.”
Will he always be a quiet enigma with bags of talent but perhaps not the personality and drive to get where he could be?
“I have grown up a lot from moving over to Bristol; a lot of people said that I was a home bird but I took a risk going there and got back into enjoying rugby again,” he insists.
“I want to prove some people wrong. I’ve got a bit of unfinished business coming back to Wales and I wouldn’t have been able to achieve what I wanted to, playing for Wales, at Bristol.
“Enjoyment is what makes me tick – if you’re enjoying it, things come much easier and I am enjoying it here at the Dragons.”
When the plaudits of the past are put to him, Williams replies: “That was a long time ago. Hopefully, I will make some new memories.”
If he does, the question marks hanging over him may finally be answered in the right way.
The world remains his to grasp. It’s down to him now.
