RoberRed is right that stakes matter, but stakes don't require a clash. I define a clash as rivalry that prioritizes beating the other side over playing well, and that's the key difference. A fierce but respectful rivalry can raise the stakes and produce legendary matches. A clash, though, actively rewards cynical tactics, time-wasting, and even violence, because the result trumps the performance. The World Cup is memorable when teams play beautiful football under pressure, not when they kick each other to stop a counterattack. If we frame sport as a clash, we excuse the ugliness and call it passion. I'd rather keep the stakes and drop the hostility.
