Based on the list I would have to go with either Serena Williams or LeBron James can't decide.
Nonsense.
Roy Jones became the Heavyweight champion in 2003. He moved up from Welterweight. Granted he lost a gang of fights at the end of his career but he's the only boxer to move up from welterweight and become the Heavyweight champ.
And Barry Bonds broke the home run record in the 21st Century so his name belongs up there.
Bo Jackson and Deion Sanders didn't even play in this decade.
