Steve Borthwick and Warren Gatland both had rude awakenings in their new roles as England and Wales were both beaten on an exciting first day of this year's Six Nations.
England were beaten by a brilliant Scotland performance at Twickenham - the Scots first win at a packed England HQ since 1983 (the win two years ago was played in front of empty stands due to lockdown), and their first back-to-back victories in south west London ever. Brilliance from Duhan van der Merwe with two tries - the first an all-time great score - helped Gregor Townsend's men to a deserved victory.
Scotland were bold and brave and hung on in the contest when it threatened to get away from them after half-time, weathering the pressure of everything that England threw at them.
In a game of fine margins the hosts far from disgraced themselves but were undone by visitors' fight and brilliance.
In Cardiff Gatland's return to the Wales hot seat was a losing one as Ireland raced away to an early 27-3 lead that they never looked like relinquishing.
Gatland defended his team, saying he saw plenty of positives after the break when Wales attacked but were unable to make their time in the Ireland 22 count.
While, grand slam champions France got their Six Nations campaign off to a winning start with a 29-24 victory over Italy, but they survived an almighty scare in Rome.

Latest results table
How to watch the Six Nations live
Every game in the championship will be aired live on either BBC or ITV.
BBC lost the rights to broadcast France's home matches in the men's Six Nations in 2022, which means that all matches in Paris will be shown on ITV. England matches are shared between the broadcasters, who began sharing rights across the competition in 2016.
S4C will be showing all Wales matches live, and RTE will have live coverage of seven of the 15 matches, including all Irish fixtures.
