Fighters who could jump up and down the weight class?

[cotto20]

First fighter that springs to mind is henry armstrong, then there is les darcy, harry greb, micky walker, tiger flowers, barbados joe walcot, sam langford and thomas hearns. Who else?

[McGrain]

Archie Moore.

He'd rocket up to 195-200 for someone like Valdes, at HW, then work back down to 175, in six of seven weeks and defend his LHW title. Amazing, really. Burning of 25lbs in a hard six weeks and then stepping in at the highest level.

Looking at Boxrec he did Buddy Turman at 203 and then got back down to 175.
