The news has shattered the backboard of our collective consciousness like a particularly aggressive dunk from the afterlife. Jason Collins, the NBA's first openly gay player, has shuffled off this mortal court at the tragically young age of 47. British sport, a realm that usually reserves its standing ovations for horses and men who can kick a ball very hard, has paused to salute a man who redefined courage in trainers.

Let us be clear: this is not a man who merely played basketball. This was a man who, in 2013, announced his sexuality with the same matter-of-fact dignity as ordering a cup of tea, and in doing so, shattered a homophobic backboard that had been reinforced since the days of short shorts and even shorter minds. The NBA, that gladiatorial arena of millionaire giants, had never seen its like. Collins, a journeyman center known more for his defensive grit than his scoring, became the standard-bearer for a quiet revolution. He did not dance. He did not trumpet. He simply said, "I'm gay," and the world, for a brief moment, stopped dribbling.

Now, British sport, that peculiar institution that worships at the altar of the Premier League and the Wimbledon queue, has offered its respects. The Football Association, a body that has spent the better part of a decade trying to convince us it cares about diversity while its terraces still echo with the odd howler, released a statement. The Rugby Football Union, masters of the grunting scrum and the post-match pint, issued a tribute. Even the Lawn Tennis Association, that bastion of Pimms and polite applause, acknowledged the loss. It is, one might say, a rare moment of unity. A collective recognition that Collins did not just play a game; he altered its DNA.

But let us not pretend this was easy. When Collins came out, he was the only active player in the four major American sports leagues to do so. He was a pioneer, but pioneers get shot at. There were whispers. There were sniggers. There were, one imagines, some very awkward team showers. Yet he persisted. He played. He fouled out with grace. And now he is gone, taken by a sudden illness that no amount of crossover dribbles could evade.

The tributes have poured in from across the pond. President Obama, who has never met a sporting analogy he didn't like, called him a hero. LeBron James, who may as well be a deity in trainers, said he opened doors. But here, in this sceptred isle, we must ask: have we truly learned the lesson? Our own sporting institutions, for all their well-pressed suits, still have a way to go. The Premier League has exactly one openly gay player, and he has faced abuse. The county cricket circuit remains a fortress of laddism. Jason Collins did not just change America; he held a mirror to the world, and our reflection is still a little blurry around the edges.

Still, let us drink to him. A gin and tonic, perhaps, with a twist of lemon and a dash of defiance. Collins proved that a person can be both a giant and a gentle soul, both a competitor and a crusader. His legacy is not measured in points or rebounds, but in the hearts of every young athlete who has ever felt the cold sting of prejudice. He made the court a little wider, the game a little fairer.

In the end, the final buzzer has sounded. But the game goes on. And somewhere, in a gymnasium full of echoes, Jason Collins is still playing. He is the man in the middle, the center of attention, the one who taught us that the most important statistic is not your score, but your courage. Rest in peace, pioneer. You have no idea how many lives you changed. Or perhaps you do. That is the kind of man you were.
