"I think everyone was just trying to take it all in and make sure we remember all these moments because it's a pretty special thing today".
Best, who is still to agree a new contract which would take him through to the World Cup, said the end result on Saturday was the reward to Sexton for his sublime drop kick in stoppage time that rainy day in Paris. "Johnny Sexton, Conor Murray were enormous today, CJ (Stander) and Peter O'Mahony were fantastic". Tadhg Furlong is still young for a tighthead, Andrew Porter coming on to lock the scrum down at only 21.
Asked to compare his two Grand Slam successes, Best replied: "This feels more special, not only because I have started every game but also because of captaining the side". The RFU media team are not happy about the impromptu Irish media gaggle blocking the corridor and we are scolded in hushed tones on a couple of occasions. "Youthful enthusiasm is being tempered by the experienced guys who have been here before and that blend is working very well for us". We wanted a Grand Slam and I think we'll look beyond that at a later date.
It is the best but it can still get better.
In beating England at Twickenham yesterday afternoon, Ireland have further consolidated their position as the second-best team in the world and in doing so, have closed the gap on New Zealand at the top. In terms of results we have, but in terms of where we want to go as a team, we are moving forward.
We have spoken about leadership density - having more leaders on the field - and that is something that is a slow burner, you have got to build that, you have got to keep working on it.
The visitors' third try came on the stroke of half time thanks to a fine finish from wing Jacob Stockdale, who became the first player ever to score seven tries in a single championship.
"It's our mentality to go and attack", said Best. "We just have to decide if we have the time to get them ready for the World Cup".
"But when you have momentum, sometimes either side of half-time teams can switch off a little bit and you can capitalise. That was following through on our mentality and what we had committed to all week".
