UFC champions Anderson Silva and Jon Jones have been nominated for ESPN’s prestigious ESPY Award for “Best Fighter” for the second consecutive year. But can either of them edge out last year’s winner, boxer Floyd Mayweather Jr. , who is also nominated again this year? Rounding out the 2013 nominees are Mayweather’s fellow boxers Danny Garcia and Canelo Alvarez. This is the third time each for Silva and Jones to be nominated for the award. Jones has been nominated three years in a row, while Silva was nominated for the award in 2009, 2012, and 2013. Silva (33-4) has not lost in the Octagon since making his UFC debut in 2006. He has won 16 consecutive UFC bouts, has held the middleweight championship since late 2006, and set numerous other records.
