Wales and British and Irish Lions second five-eighths Jamie Roberts has been around the game long enough to have an opinion worthy of respect.
A qualified doctor of medicine, he has 94 Tests for Wales, and experience in England's Premiership, France's Top 14, Super Rugby and the Celtic League.
It was his Covid-19 interrupted run with the Stormers in Super Rugby earlier this year that led to something of a rugby epiphany for him as he renews his acquaintance with rugby in his home country in playing for the Dragons and also pursuing a return to Test rugby.
Roberts was impressed with the greater opportunity to use individual skills within the team plan in that Super Rugby allowed.
"Down there it's more one on one collisions and you can use your footwork and off-load a bit more, he told walesonline.co.uk.
"There's more space in Super Rugby because the speed of the ball and the pitch is quicker.
"Players' hand speed is quicker so you have to defend the full width of the pitch," he said.
"When you have to do that space opens up in the middle of the park. The collisions are one on one, not one into two like they are up north.
"If you defend too narrow down there they just go pass, pass, pass and score in the corner.
"The style of rugby there gives you the opportunity to use your footwork in the middle of the park," he said.
Roberts said he felt his experience in Super Rugby, brief as it was, had made him a better all-round player, and for him, it was always a case of continuing to develop and improve as a player.
"I have been challenged later in my career, whether that's privately or publicly, to go and develop a skill-set and try and become an all-round player," he said.
"That can go one of two ways: Either you embrace it and you try and become a better all-round player or you try and do what you do best and do even better.
"There's no secret to the way I've learned the game over the years. I like to think I have brought value to the teams I've played in.
"I enjoy the confrontation side of rugby but it's adding subtly around that, the off-loading game and a bit more footwork.
"Super Rugby allowed me to do that a bit better because there's a bit more space on the field compared to in the Premiership, where you end up running into about three players."
Roberts was hopeful his work in improving his play would be showcased for the Dragons.
"I am never going to be a second outside-half playing 12. That's not me and I have never tried to be. What I want to be is a better version of Jamie Roberts," he said.
Roberts is also pushing the message that players have a role to play in the recovery from the coronavirus pandemic in Wales.
"As players, we have a bigger responsibility than ever to help motivate communities to, one, come back and watch us and, two, make rugby the heartbeat of it.
"That has always been the casee. On the back of this pandemic, we can't afford to lose that," he said.
It was especially important because he was concerned the next generation was not so enamoured of the game and he believed rugby was in a precarious position, far more than many appreciated.
