Who has quicker/better hand speed?..Mayweather or Calzaghe?

[The Surgeon]

Theres a reason for that though.
At 140 Floyd threw lots of extremly quick combos, and he showed signs of that against Mitchell.
However, he had to deal with Zab, who is extremly fast at 147 and then Baldomir, who he threw nice combos early against but his injury reduced him to potshotting more than normal.

Id say thats an accurate assesment
