Have fast hands.

ways to do it as a southpaw? lol its probz just as easy doing it as southpaw than orthadox, look at zab judah, hes basically a southpaw lesser version of floyd, wen the guy jabs(ortahdox) roll with ur low right hand shoulder, wen the guy throws a rite hand roll with ur high left hand etc. people make the mistake tht floyd is the onli 1 ever with tht roll shoulder style, and tht the mayweathers invented it, naww man, archie moore, ray robinson, james toney and pbf u shud all study how they do it.
