There has been a massive worldwide shift in the interest of basketball over the last 20 years. You clearly don't follow basketball at all.
Of course, given the fact your location says UK, given how bad the UK team has been, I don't blame you for wanting to get rid of basketball.
But if you DID follow basketball, you'd know it's experienced a MASSIVE upswing in interest across the world. In fact, I'd say it may very well be the fastest growing sport worldwide right now. Just to be clear, I'm not saying it's the most popular (obviously), but I think it's the fastest growing sport in the world.
I suggest you do a little research. You would find there has been a global shift in interest in basketball in the last 20 years. For example, back in 1992 when NBA players were first allowed to play, nobody knew ANYONE's name who wasn't on Team USA, including Team USA. Today, Argentina has 4 NBA players on their team. Spain has have 5 NBA players, and I think Rudy Fernandez has played in the NBA. France has 6 NBA players.
The difference between Team USA and those countries is still depth (and LeBron James and Kevin Durant), but to insinuate Team USA dominates in the same manner they dominated 20 years ago is simply false. And as time goes on, it will become more and more competitive.
By the way, with America's win in the women's soccer/football, they have now won all but one gold medal in the Olympics (the other was a silver). Should we eliminate soccer from the Olympics, since America has been so dominant?
