We had Brian O'Driscoll in studio on Friday night talking all things Six Nations, when quite a few listeners voiced concerns over our 'over-reliance' on Johnny Sexton. BOD admitted that if Johnny's increasingly quirky hamstrings were to give up around World Cup time, we'd be in 'trouble, big trouble'.
But he went on to qualify the remark, saying that Sexton (below) isn't just the best out-half in world rugby at the moment, he is quite probably the best player full-stop in the world at the moment.
It is, therefore, perfectly natural that we're so massively reliant on the great Johnny's talents. He's just that good.
And what a wonderful thing it is for us to have the Lions out-half orchestrating our play. Better still is the seemingly telepathic relationship he happens to have with the undisputed best coach in the northern hemisphere.
Our nerves jingle because it's all so beautifully aligned in a World Cup year. Few teams achieve a perfect balance across 15 positions. There are always players on the rise and the slide. And some will simply be more equal than others. An over-reliance on Johnny Sexton at his peak is a beautiful problem to have.
