[1] He is now an international coach, currently serving as director of rugby at Leeds Tykes, whilst running his own sports consultancy company.
It was during this period that Welsh packs became far less dominant than in the glory days of the 1970s and Davies, along with David Pickering and Bob Norster, was one of the few class forwards that his side could muster.
The mustachioed Davies was a useful addition to the side mostly because of his offensive ability and the fact that he could play either as flanker, number eight or lock forward.
His career is also memorable for his involvement in the so-called "Battle of Cardiff" in 1987, an extremely violent clash between Wales and England that saw Davies punched by opposition lock Wade Dooley.
England, who had not won in Cardiff since 1963, led the game 15–12, before fullback Chris Martin failed to take a high kick and Davies (Jonathan) scored a crucial try.
The following year Davies played in seven tests in total, but was denied a possible Triple Crown when his side were beaten 21–18 by England in the first match of the campaign.
Davies and his teammates then embarked on a short tour of the Southern Hemisphere as part of the side's preparation for the 1987 Rugby World Cup and included victories over Fiji, Tonga and Western Samoa.
Despite winning six games during the season, and performed well in the 2001–02 European Challenge Cup, they finished bottom of the table, but avoided relegation due to the inadequacies of Rotherham's ground.
On 19 January 2013, Davies earned his first Heineken Cup win, after beating Sale Sharks 26–14 in the final pool round of the 2012–13 season.
A final pool round loss to Exeter Chiefs, 19–13, meant the Blues narrowly missed the quarter-finals of the 2013–14 European Challenge Cup.
After Namibia's 2014 end-of-year tour, Davies was appointed as interim head coach for North Wales region RGC 1404.
He helped see RGC promoted up to the Principality Premiership for their first ever time, before standing down as head coach at the end of that season to concentrate on his duties with Namibia.
[9] After leaving Cardiff in March 2014, it was announced in November that year that Davies was appointed as technical adviser for the Namibian national side ahead of the 2015 Rugby World Cup.
He remained with the side during the 2015 World Rugby Nations Cup as an adviser, and after losing all three games then head coach Danie Vermeulen stood down on 25 June 2015.
In 2016, Davies led his side to second place in the 2016 World Rugby Nations Cup, only losing to Romania 20–8 in the opening round.
On 3 January 2020 Yorkshire Carnegie (the former name of Leeds Tykes) announced that Davies had returned to Headingley as Director of Rugby replacing Martyn Wood.The club were bottom of the Championship having lost their first 13 games of the season.
[12] With Davies' help, Worcester remained in the top flight competition with key victories over leading teams Harlequins 24–17 and Saracens 24–18.
