Here's the Ireland squad for the championships. Stand out name would be Paddy Jackson, who although he had a poor HEC final was very impressive in Ulster's semi final. Other than him there are maybe 6-7 players who've had Pro12 game time this year.
The team finished 2nd in the 6-nations and only lost to England in the grand slam decided in the final game.
