Farrell added he was “proud as punch” about Ireland’s performance, and said there was a bigger picture to this year’s tournament.
Ireland started the Six Nations by losing to favourites France, but responded with a gritty win over Italy.
They impressed in a victory over England, but were then pushed all the way by Wales in their penultimate game in Dublin.
“Winning matters but what’s happened over the eight weeks matters more to us in the sense that there is a lot of firsts, with first caps, first Six Nations and first taking it to the final week when it matters for quite a few people in our group,” Farrell added.
“How our group have come together and navigated their way through that is pretty special so we grow massively because of it, and the group has become more resilient because of that.”
While the destination of the Six Nations trophy is out of their hands, Farrell reiterated he was delighted with another piece of silverware.
“That’s five trophies in five years for us,” he added on ITV.
“I know it’s a Triple Crown but it’s hard to win over the years for Ireland and we’re proud of that.”
