Back to the thread for a moment?
All sports should have a defining moment. With football, you cna walk away, arguing about the penalty, goal, offside decision, or whatever, that turned the game. There is usually a defining moment to that sport.
Rugby probably also has it, and golf sometimes (if you saw Sergio at the US PGA drop it in the water, for example.) Tennis to a degree, boxing, and track and field can have it, but not darts, rarely snooker, or gymnastics.
Other sports simply don't. When Lewis Hamilton leads from start to finish, there's no 'moment' and therefore it's not a proper sport.
Basketball - you shoot and score. Then we'll have a go. Then you try again. Eventually, someone will have more points. No defining moment. Same goes for Baseball (how many innings do they want, ffs?) and swimming.
