We have an expert panel that votes on ESPN.com's pound-for-pound top 10, of which I am one member. It's a way for us to reach some sort of consensus on the best fighters in the world, regardless of weight class.

But since we began using this method, rarely does a day go by where a #FightFreak doesn't hit me up on Twitter or Facebook asking for my specific top 10. I appreciate the interest in my opinion so since we're at the halfway point of the year -- and it's a slow boxing weekend -- I am here to serve. Here is my top 20 pound-for-pound list. Agree or disagree, it's all good.

1. Floyd Mayweather Jr. (46-0, 26 KOs): Not a complicated pick. The junior middleweight and welterweight champ is universally regarded as the best fighter in the world. He tops the ESPN.com poll and my personal list, even as he heads into the twilight of his career. If only he would stop disappointing fans around the world by finding ways to avoid Manny Pacquiao. Even when Mayweather had a bit of a tough time with Marcos Maidana in May, he still was the clear winner. Mayweather is so good that it is a shock when an opponent wins even a few rounds.

2. Manny Pacquiao (56-5-2, 38 KOs): Boxing's only eight-division titleholder had a rough 2012, getting ripped off in a horrible split decision loss to Timothy Bradley Jr. and then getting drilled by Juan Manuel Marquez in a fight he was on the verge of scoring a knockout victory of his own. But he rebounded strongly, pitching a virtual shutout against Brandon Rios, and then avenging his loss to Bradley in April to regain his welterweight title in an outstanding decision win. Pacquiao looked great.

3. Andre Ward (27-0, 14 KOs): The super middleweight champion is an awesome talent, which he displayed by tearing through the Super Six World Boxing Classic, easily beating top opponents in Carl Froch, Mikkel Kessler, Arthur Abraham and Allan Green, not to mention a non-tournament win against Sakio Bika. Then he brutalized then-light heavyweight champ Chad Dawson, who moved down in weight to challenge him, followed by a rout of contender Edwin Rodriguez. Ward has had injuries sideline him for long stretches, but the main reason he's had only two fights since December 2011 is by continuing to battle promoter Dan Goossen over seemingly small issues. He is losing valuable years of his prime.

4. Wladimir Klitschko (62-3, 53 KOs): The heavyweight champion isn't blessed with a deep division of contenders, but he has skills, a brutal jab, an awesome right hand (best in boxing), underrated defense and has mowed down everyone put in front of him. He has never ducked anyone, beaten the best out there and unified three major belts during his historic career. Since his second title reign began in 2006, he's defended the title 16 times (12 KOs), third most in heavyweight history behind Joe Louis (25) and Larry Holmes (20). His eight-year-plus reign is second all-time to Louis' record 11 years, 8 months, 8 days. The 1996 Olympic gold medalist is 23-2 overall in world title fights. He deserves a lot more respect that some people give him.
