How important Ireland is for this game is shown in Joe Schmidt's "Come and Have A Go" selection, including the fact that Tadgh plays Beirne blind. Henshaw and Aki have been reunited since their Connacht days, which will give the Samoans midfield some physical challenges. Jonny Sexton is back and has to show his form. I'm honestly not sure if he's fit, which does not help.
Henry Taefu will cause some problems for Ireland, the center is a bit small, and Vui, Ioane and Lam could give their Irish colleagues a hot day as they get their wheels rolling early.
