In his first year as a professional boxer, Manny Pacquiao fought 10 times. In Floyd Mayweather Jr.’s second year as a pro, he also fought 10 times.

By the end of 1997, Pacquiao’s third year, he had already fought 23 times, or 38.9 percent of his total. By the end of 1998, Mayweather, in his third year, had fought 19 times, or 45.2 percent of his career total.

That is a sad reminder of what might be in boxing. The top stars simply don’t fight enough anymore. Mayweather, who is No. 1 in the new Yahoo! Sports boxing rankings, has fought 10 fights combined since 2005. Pacquiao, who is No. 2 in the poll, has fought only nine times since 2008. And Sergio Martinez, Yahoo! Sports’ third-ranked fighter, also has only had nine fights since 2008.

The reason they’re so inactive, of course, is money. The fighters command massive purses now and promoters can’t afford to pay them the kind of money they demand in order to fight more than once or twice a year. Mayweather hasn’t fought as much as twice in a year since 2007 and neither Pacquiao nor Martinez has fought as many as three times in the same calendar year since 2008.

The great Sugar Ray Robinson fought 10 times or more in a year eight times. He had a high of 20 fights in 1941, but even as his career waned, he fought 10 times in 1964 and 14 times in 1965.

How much better off would the sport be if either Mayweather or Pacquiao fought 10 times in 2012? If the fighters would agree to take less – a few million per fight for a handful of less-than-major bouts per year against slightly lesser opponents – the interest and excitement in the sport would rise dramatically.

The biggest stars attract the most attention. The extraordinary attention paid to talks over the last two-plus years about a potential superfight between Mayweather and Pacquiao is proof of that. It seems as if there have been as many words written since late 2009 on a fight that hasn’t happened and that may never happen than there has been on the bouts that have occurred.

Find a way to get the top 10 or 15 guys to fight four to six times annually instead of one to three times and you’ll be credited as the person who revived the sport.

There is nothing wrong with boxing that a little activity from its biggest stars can’t fix.

With that, let’s go to the newest Top 10, in which none of the fighters had a bout since the last rankings came out. Four more votes were received this month than last, 38-34, so there was one minor change in the ranking.
