Covid-19 has been better at wrong-footing people than Brian O'Driscoll. When the virus was beginning its European tour back in March, various governing bodies were intensely relaxed about its approach. Full rounds of domestic sports leagues were played, rugby internationals and racing festivals were held, fans were allowed to travel from already-affected countries to other soon-to-be-affected ones.
The unfolding carnage in Italy brought things to a halt.
But when the lockdowns began most people believed that in a couple of months' time sport would be able to pick up where it had left off. The full scale of the change which would be wrought by the virus was not clear.
It wasn't long before our illusions were shattered. One by one the summer's fixtures - Wimbledon, the British Open, the Olympics - began to be cancelled.
Things began to take on an apocalyptic hue and it seemed that spectator sport would become a thing of the past until the discovery of a vaccine, which would not happen soon and might not happen at all.
When the Dutch, Belgian and French football authorities announced the cancellation of their domestic seasons it seemed as though the sporting summer's death knell had been rung. And when GAA president John Horan (pictured) implicitly cast doubt over not just this year's but next year's championship he seemed merely to be stating the obvious.
The one light on the horizon was the declaration by the Bundesliga that it intended to restart in the middle of May. But this looked overly optimistic and it seemed likely that the rest of the continent's leagues would follow the French rather then the German lead. Sports journalists prepared to compile lists of their favourite 5,000 sporting moments.
But look where we are now.
Not only is the Bundesliga back but so are domestic leagues in Portugal, Poland, Austria, Croatia, Denmark, Bulgaria, Serbia and Hungary. The Premier League, La Liga and Serie A should all be back within a fortnight. The Formula 1 season will restart early next month.
A Champions League final tournament is being planned for the start of August in either Germany or Portugal. A full slate of Classics, a Royal Ascot and even a Galway Races are on the cards for fans of the gee-gees.
Friday's announcement that the English Premiership is targeting an August 15 resumption was a dramatic illustration of the change in mood given that rugby was the sport whose return seemed least possible not too long ago. And there's even a chance that cricket's 20/20 World Cup, which looked a definite goner a few weeks back, might take place as scheduled in October in Australia.
UEFA president Aleksander Ceferin has suggested we might see spectators back in European stadiums before too long. The news from New Zealand is that spectators could be admitted to games as early as next week with the Super Rugby clash between the Highlanders and the Chiefs on Saturday earmarked as the game to bring the sound of applause back to the sporting world.
Even the GAA has been infected by the spirit of optimism. Surveys have been done to assess the risk posed to players in the event of a return to action. Whereas a few weeks back the 2021 championships seemed to be in jeopardy, now it seems possible that the 2020 renewal might not be doomed after all.
All this is great. And it mirrors what's happening in countries like our own where infection rates have decreased dramatically and lockdown restrictions are by this stage being honoured at least as much in the breach as the observance.
But isn't there a possibility that the current optimism might be just as ill-founded as the complacency of March and the pessimism of April turned out to be?
Hasn't every other prediction been wrong so far?
