Don't know if any legal but alot of fighters didn't go by their original names

"Marvelous" Marvin Hagler jumps out as the biggest name. Dwight Braxton becoming Dwight Muhammad Qawi is another name fighter who did it.

Smitty gets a thumbs up from the blogbaba, I should have read his answers before I gave the Qawi answer.

I DON'T KNOW IF LEGAL BUT THESE BOYS DID:

ROCKY FROM ROCCO M

ROBINSON FROM WALKER SMITH

WALCOTT FROM ARNOLD CREAM

QAWI FROM BRAXTON

SAAD MUHAMMAD FROM M. FRANKLIN

MASTAFA MUHAMMAD FROM E. GREGORY

P. S. THAT WAS FROM THE TOP OF MY HEAD, THERE ARE PROBABLY MORE.

Can't think of any others than these guys already wrote.
