True dominance is hard to achieve in boxing. To mow down fellow prospects and reach contender status takes tremendous natural talent and sustained focus over years.
To reach the top and remain there for fight after fight and year after year is rarer than even serious fans sometimes seem to realize. Even in today's era of carefully selected opponents, when a fighter can collect titles while winning 30 or even 40 straight bouts, it is an historic accomplishment.
This is not a golden age for boxing on the level of the 1940s and '50s or '70s and '80s. But this list of dominant performers from the past decade demonstrates that there is greatness in any era.
