Of the new signings, Jonny Sexton will obviously be a huge improvement at 10 and hopefully bring some urgency and direction to the back line which has been sorely lacking. Mick Kearney will prove strong competition for the top 23. Ian Hirst comes from the AIL and although well stocked at loosehad, Leinster are probably right to bring him in for a look given his pedigree (AIL player of the year nomineee) at club level. Royce Burke Flynn is simply a cover option given the other three tightheads could be World Cup bound.
What stand out is the lack of depth at centre which may explain the re-signing of Collie O'Shea as one of only three senior contracted players during the World Cup period. Hopefully it provides opportunities for the likes of Garry Ringrose and Tom Farrell to get some game time.
