Ireland's bench press was so good in this Six Nations that Rob Herring believes a World Cup triumph has to be next on this squad's agenda.
During his time with England, Eddie Jones talked not of replacements but of 'finishers' - and that's exactly what Ireland's men in reserve turned out to be during the successful Grand Slam charge.
Fittingly, it was one of those replacements - Herring, in this case - who put the icing on Ireland's cake on Saturday with the fourth try before the finish.
