Rob Henderson's decision to join Munster from Wasps on a three-year contract was a huge fillip for the province and the IRFU. Henderson himself will decide which club he will be attached to - although next year the contracted players will probably not see the inside of a club changing room. It would be surprising if Peter Clohessy doesn't draw on his friendship with the player to invite him down to the "yellow brick road" and a place in Tom Clifford Park.
