Vince attended West Mon School and Bristol University. He also played for Pontypool. Three Welsh caps were won in 1924 against Scotland (a 35 v 10 defeat at Inverleith in which he scored a try), Ireland (a 10 v 13 defeat in Cardiff) and France (a 6 v 10 victory in Paris in which he scored a drop goal). A British Lion tourist to South Africa in 1924 he played 13 games (6 at centre). Played for Newport v  Maoris 1926 (Draw 0 v 0) and New South Wales Waratahs 1927 (Lost 3 v 20). Newport captain 1928-29. At the time of his death he was Chairman of Newport Athletic Club.

The following Annual Report recorded:-

"In the ninety odd years of its history, the club has been extremely fortunate in the large number of its members who have given voluntary service in many directions. Only those who are involved in the inner workings of the club which covers so many playing activities and a large social centre, can appreciate how much it depends on the loyalty and sacrifice of such members. Vince Griffiths was a wonderful example of a man who felt all this was worthwhile to a club which he said on many occasions had done so much for him."

"Much has been said of his contribution to Welsh Rugby and there is no doubt that his great knowledge of the game and his refusal to be stampeded into any decision, unless he felt it was in the interest of the great amateur game he loved, gained the respect and affection of all with whom he came into contact."

"Within our own club his contribution to the Rugby side is well known. As a player he was captain in the seasons 1927-28 and 1928-29 and a member of the British Lions team that toured South Africa in 1924 and as would be expected of a player of his ability, a Welsh international. His wisdom and prudence played an integral part in maintaining the Newport Athletic Club as one of the great institutions of both town and county. His outstanding attribute was his absolute integrity; his word was his bond. He never forgot a promise and one could always rely on a confidence which placed with him would never be disclosed."

In 1968 a Memorial Sevens was organised in memory of Vince Griffiths and another club stalwart, Bill Everson. The programme included the following by Western Mail journalist J. B. G. Thomas:-

"Vince and Bill"

"AN APPRECIATION"

"By J. B. G. Thomas"

"The names of Vincent Griffiths and Bill Everson can never be parted from the short list of great names hallowed at Rodney Parade. By their service and devotion they have become as much a part of the Newport Club's history as the very buildings and stands which have housed so many excited sup­porters. Thus it is fitting on this special day to write a tribute to two players and officials who maintained the highest ideals of the game throughout their lives."

"Their passing was a sad loss to the club and it is not easy to fill such gaps even from the list of worthy helpers who now tend the affairs of the club. It is still a pleasure to visit Rodney Parade and to know that it is still being run in the way that Vince and Bill would have liked. The warm hospitality remains as the fortunes of the teams change on the field of play with success and failure being tasted."

"They were passionately devoted to the cause of amateurism in the game and developed under the guidance of one of the game's outstanding admin­istrators, Horace Lyne. He was, for so many years, Mr. Rugby in Wales. An original member of the International Board who held almost every office in the game and at Rodney Parade; he set the pattern for the rather stern devotion to amateurism, which has never been ignored." 

"Another outstanding figure who guided them in their early days was Tommy Vile and so they had much to follow, much to emulate, and they did it well. Both played with distinction for the club for many years, and both played in the scarlet jersey of Wales. Vince became a British Lion in 1924 and played with enthusiasm in several positions, in the warm land of South Africa." 

"Bill was a brave full-back who shirked nothing on the field of play, and suffered many an injury for his daring in diving at the feet of oncoming forwards. He got one cap in 1926, but was reserve on numerous occasions, and his contribution to the game should not be measured in the number of caps earned but in loyalty, especially to his club. He loved the black and amber colours and guarded what they stand for with an intense devotion."

"As secretary of the club he was remarkably efficient and only his family can really say how many hours he devoted to the administration, and suffered in the cause but they, too, are equally devoted and the Eversons were, and still are, a large part of the club." 

"Vince was a bachelor, and was "married" to the rugby game. He served for many years as a member of the Welsh Rugby Union, and never was there a better selector, for his approach was ideal. He was a good listener and he suffered fools gladly rather than reveal the secrets of the committee room. He accepted criticism as he accepted praise and treated journalists with a kindly tolerance." 

"He believed that everyone was entitled to an opinion on the game, but would rush to the defence of any player or official under unfair "fire". Vince, like Bill, was a good friend and it was a pleasure for me to talk rugby to him. He enjoyed discussing technicalities and new trends in the game, and he was always delighted to see Wales win and win well, whether or not a Newport man was a member of the side."

"Yet within the club he was one hundred per cent for it and then some, but it was his sense of fairness that appealed to his friends. I can see them now, Vince and Bill, for Vince would welcome you by opening his large cigarette box and offering a smoke. How many thousands of cigarettes did he give away?. Bill would offer a programme and say, "Don't forget a cup of tea, afterwards!" " 

"They were true men of Rodney Parade. Great men in the game. R.I.P."
