Didn't really get much of Hamed this decade - a shame... I think you need to mention the Mexican fighters at the lower weights, particularly Barrera, Morales and the Marquez brothers.
I think overall its been a great decade - some fantastic rivalaries - Vasquez vs Marquez, Barrera vs Morales, Gatti vs Ward, JMM vs Pacquaio are the four that stick out. But then there was some other ones like DLH vs Mosley, Vargas vs Mosley, Lewis vs Rahman (unecessary but it got us talking), Forrest vs Mosley, Mormeck vs Bell, Pac vs Morales, Woods vs Johnson, Tarver vs Jones, Calzaghe vs Veit (

)
Whilst from an "all British" perspective we did again miss out on Hatton vs Witter, we got Enzo vs Haye which was much hyped and nice to see a true unification involve two Brits.
Could have so many "awards" and there would be so many different angles.
I can start - "performance" of the decade.... single fight performance. We could probably think of close to a hundred different responses to this all with good cases - here are some worth noting though.
HOPKINS vs Trinidad.
MOSLEY vs Oscar (possibly the one I will pick).
CALZAGHE vs Lacy
MAYWEATHER vs Gatti
MAYWEATHER vs Mosley
PACQUIAO vs Oscar
PACQUIAO vs Barrera 1
PACQUAIO vs Hatton
PACQUIAO vs Cotto
PACQUIAO vs Margarito
BARRERA vs Naz
MORALES vs Pacquiao 1
HOPKINS vs Pavlik
MOSLEY vs Margarito
And thats without mentioning the performances of arguably the P4P #1 of the decade - Roy Jones Jnr. I don't think Roy gets my vote, and the fact that he doesn't showcases how fantastic some of the fighters in the latter half of the decade have been.
