So Jonny Sexton is leaving Dublin for France.  Bit of a blow, that, but the French simply offered too much money.  Can't blame the guy.  He will, of course, still be available to play for Ireland.  Will this be the start of a widescale move of Irish rugby players to greener, French pastures?  On the plus side, it gives an opening for another young Irish No 10 to develop (eg Madigan) whilst Jonny keeps playing in France.
