Five things we learned from round three of the Guinness Six Nations

Ireland and Scotland savoured victories in the third round of the Guinness Six Nations and Italy claimed an historic 13-13 draw against France, the first time the Azzurri have avoided Championship defeat away to Les Bleus.

Here, we look at five things we learned from the weekend’s action.

New technology surrounding mouthguards are concerning Scotland head coach Gregor Townsend. Scotland temporarily lost a second player in successive Six Nations matches for a head injury assessment triggered by the new technology. This championship is the first time elite male players have worn ‘instrumented’ mouthguards that send alerts whenever a ‘head acceleration event’ with G-force that exceeds 70g and 4,000 radians per second squared is detected. But Townsend said after Calcutta Cup success: “There’s a bit more work to do before this technology is correct.”

No side has managed back-to-back Grand Slams in the Six Nations era, but Ireland are within two games of doing so and it would take a brave punter to bet against them. Ireland recorded an 18th straight home win with a routine 31-7 success over Wales, equalling England’s Six Nations record of 11 consecutive victories. Andy Farrell’s side did not even have to produce their best to claim a third bonus-point win from three games – and now only England at Twickenham and Scotland in Dublin can stop Ireland holding another Grand Slam party.
