Take Jonny Wilkinson with the Lions? Do it when he is 33, 34 next month? Turn back the clock, deliver a crushing blow to his anointed successor, the potentially iconic Owen Farrell? But what else could you possibly do?
The Lions coach, Warren Gatland, scarcely has a choice. Not if he wants to live in the reality of the performances of the hour and the day rather than the tyranny of time Wilkinson so brilliantly rejected at Twickenham yesterday.
We see many resurrections in sport. We see much resistance to the dying of the light. But how many boxing rings and test grounds and racetracks and football fields do we have to revisit to see again something quite as perfect as the show Wilkinson put on at Twickenham?
Sadly, the old place at which Wilkinson was appearing for the 46th time had far too many empty spaces on the terraces to be the perfect shrine for one of the nation's greatest sportsmen.
Wilkinson did so much more than carry Toulon to the final of the Heineken Cup with all 24 points in the victory over Saracens.
