Is Pacquiao the only fighter to won Three The Ring Titles?

Henry Armstrong
Sugar Ray Leonard

Floyd Mayweather would've been, but they re-did their policy right after he left 130.

Oscar De La Hoya also probably would've been, but they didn't have their belts and ratings in the mid 90s.

 

Trinidad too, at least two but not ring title by that time.

 

I know Calzaghe held two at the same time but as for three no. Doubt wed be seeing him at cruiser

 

Ring belts post 01 yeah?

Would Jones have had 3 at Middle, super middle and light heavy?

 

Benitez at 140 147 and 154, but i dont think they had a 154 belt in that time.

 

Mayweather has 3

 

The Ring had a belt at 154 at the time, but Leonard was the champ when he took it from Kalule. Then Leonard retired/vacated the title, and the Hearns/Benitez bout was for the vacant belt.
