As much as I admire both Shane Mosley and Roy Jones I think a) Shane Mosley is nowhere near the best lightweight in history and b) I could understand the claim more if Roy Jones had fought at that weight and fought Mosley. I dont think Shane could have lived with Duran in the early 70's or Carlos Ortiz. Going Back further you've got the great Benny Leonard, Freddie Welsh, Battling Nelson and Ad Wolgast. These remarks have to be taken in context... too many people are referred to as legends these days (sometimes by commentators who should really know better). For what its worth I beleive the best light weight ever was a young hungry Roberto Duran!!
