Interesting question. It's tough to name a top 10 for the decade and I'll probably miss some out by mistake but, in no particular order the fighters involved must be.

Floyd Mayweather
Roy Jones Jr
Bernard Hopkins
Shane Mosely
Oscar De La Hoya
Felix Trinidad
Joe Calzaghe
Manny Pacquaio
Marco Antonio Barrera
Erik Morales
Lennox Lewis


For me it's between those 11, although I'm sure I've missed someone obvious out.

Guys like Winky, JM Marquez, just finish outside those above imo. although maybe Winky deserves to make the top 10, not sure. Wins over Mosely and Trinidad are obviously huge.
