It was the 1990s. Unless you were a laid-off manufacturing worker in the United States or a displaced Campesino in Mexico, the economy seemed to be firing on all cylinders. Military intervention was still sporadic and rare enough that middle-class Americans could usually completely ignore it.
It was the best of the 1950s and the 1960s combined. Hip hop was yet to be commercialized, for the most part. In rock and roll, anybody who mattered was ripping off Neil Young, which made for a mini golden age.
And it was a terrific era for boxing. The heavyweight division was still high profile and contained a deep roster of talent.
The sport was full of great fighters from the lightest weight classes up. So much so that to narrow down a list to just 10 required leaving off fighters who are Hall of Famers and among the all-time best in their divisions.
