This latest installment of power rankings is about a week late thanks to my birthday. There's a new No. 1 this month, which is significant, because Arthur Abraham has been atop the list for over a year.
Alas, Andre Dirrell knocked him a few spots south, and Abraham has more tough fights awaiting him in the Super Six World Boxing Classic. It's possible he may never make it back to No. 1.
If you've never seen these rankings before, let me assure you that I don't think Juanma is a better boxer than Manny. This isn't a pound-for-pound list, but a different method of measuring performance over the last few years with a formula we devised at BoxingWatchers.com.
The formula rewards staying active, winning, and knocking people out... but only if those wins come against opponents with good records. Some top fighters (Floyd Mayweather, for one) haven't been active enough since April 2007 to be ranked by the formula.
Someone pointed out last month that this list is inherently weighted toward younger boxers who fight more often, but that's the way it goes. On with this month's scores!
