Another of the elite thirteen who represented Featherstone in their opening fixture in senior rugby league at Bradford on 27 August 1921, Billy Clements had been a member of the all-conquering junior side of 1919 to 1921 and he quickly adapted to the senior game to play a vital part in Rovers' baptism in the 1920s. It was his 'excellent pass to Jimmy Williams' which led to Williams scoring Rovers' first try at Bradford. One week later, in the opening home game against Hull, Williams repaid the gesture: 'He broke from the scrum, Clements was in attendance to take his pass and force his way over the line with three Hull defenders clinging on.' 

Although listed as a second row forward, Clements had a varied first season playing at prop, loose forward, hooker and centre as well as second row, but for the rest of his career it was predominantly second row, with the occasional move to the front row. He was very versatile and nimble considering his bulk. In his second season, he became the first Rovers player to gain county recognition when he played for Yorkshire versus Lancashire at Hull in December 1922. He made two other appearances for the County - in October 1923 at Hunslet, as hooker, when he scored a try and a goal in the 51-12 defeat of Cumberland, and at St Helens in December 1925, when he was one of four Rovers players who helped secure a 26-10 victory over Lancashire.

For a forward, he was an adept try scorer and he had two tries in each of the games at home to Barrow in April 1922 and at home to Hull in February 1924. He was also a powerful goal kicker and he broke more than one window in the houses on Post Office Road. Luckily for the local homeowners, however, he was only used occasionally as Jim Denton and Jimmy Williams were the more regular kickers.

He was part of the pack which shook mighty Wigan in the epic second round RL Cup game in March l923,when Wigan narrowly secured a 14-13 win. He also played in all three games of that incredible RL Cup first round encounter with Halifax in 1925. The Rovers travelled to Thrum Hall on 14 February and on a snow-covered pitch fought a tremendous duel at the end of which neither side had scored. The replay took place four days later in perfect conditions at Featherstone, when another tremendous forward tussle ensued. At half-time there was still no score, and even Billy Clements had been unsuccessful with his penalty attempts. A penalty goal to each side in the second half resulted in another drawn game 2-2, and so five days later, the second replay took place, this time at Headingley. Heavy rain preceded the game and after another absorbing encounter, Rovers finally won through 6-2. The games must have set up some records - 120 minutes were played before a score, and in the three games no tries were scored.

In the 1927/28 season, Clements was appointed captain, an indication of his popularity and the esteem with which he was held. It was therefore a surprise when, after leading his team to a hard fought 6-4 victory at home to Hunslet on 14 January 1928 as the Rovers strove for a top four place, he was transferred to Wakefield Trinity. This was yet another example of the Rovers having to sell one of their stars to ease their financial burden.
