Roman Gonzalez and Floyd Mayweather are both undefeated, longtime world champions. And I don't expect either one of them to lose for the first time in 2014.
At the world championship level, nothing is a sure thing. Winning 20 to 30 fights straight and collecting a belt or two is tough enough.
But of the small number of fighters who make it to that level, far fewer are able to continue winning year after year once they start facing world-class opponents every time out. Probably at least one fighter on this list will end up losing in 2014 after all.
But out of all of boxing's champions, these are the eight who are most likely to go unbeaten over the next 12 months.
