Southpaws fighting out of an Othodox stance, Why!!!

[stonemittens]

Please forgive me if this is a stupid question. (they do exist)

Why do some fighters who are left handed fight out of the orthodox stance?
I have heard rumors that Roy Jones Jr and Oscar De La Hoya are both southpaws and that Winky Wright is actually right handed but lines-up like a southpaw.
Is this very common?

Idk if it's common, but I am the same way. I just feel more comfortable jabbing with my writing hand.

[venomus_p4p]

Because it puts thier stronger hand in front as the lead (Cotto) and feels more comfortable to them (Oscar)

thanks for clearin that up for me.

because they can lead with the right hook.
