It’s one of the most exciting sports. You don’t know what you’re saying
It's actually not that popular outside of America, in fact that's the case with most American sports. They are extremely popular at home but apart from a few other countries the rest of the world doesn't follow or play them.
Basketball is probably the least boring for the 3 major sports in America. American Football is by far and away the most boring sport in the world, I honestly would rather watch darts or lawn bowling. Baseball is not far behind.
As for Basketball the problem is that the first 3 quarters of the match lack any intensity and it's almost like going through the motions. Yes sometimes the final few mins can take out but that is so predictable.
I have tried to watch as many sports as possible during this Olympics and there are some that I won't watch again for 4 years and there are some I may start following. I've really taken a liking to middle and long distance running for example. But basketball is one of those I will not follow and hopefully it never really takes off here in the UK.
Another problem with Basketball is the clear advantage being tall has, in Football (soccer), Tennis, Athletics for example there are no clear advantages with being a certain height. Messi, Alcaraz, Agassi, Modric, African long distance runners are all much shorter than their peers and there are so many other examples I could give.
All American sports are awful.
