In its greatest moments, the grandeur of boxing tends to rise above other sports. It's a roller coaster unlike anything else.
The moments of epic drama in boxing often transcend the regular highlights found in the various professional games. And at the same time, the low points of prize fighting often far outstrip other sports in terms of tragedy, shamelessness and pure disgrace.
If this was a list about most other sports, various performance-enhancing drugs scandals would dominate. Boxing has seen its share of these, too. But none of them have ever been viewed as significant enough to earn a place here.
As often as not, boxing has had even bigger image problems to worry about.
At the same time, boxing has always had the fights to fall back upon. This is a list dominated by outrageous behavior in the ring, tragedies outside of it, and corruption and incompetence behind the scenes.
But it is also a list dominated by some of the greatest fights of the past two decades.
