Name a fighter who dropped below their usual weight class and didn't get beat.

Fights are won and lost on the scales. Off the top of my head all the fighters who dropped whole weight classes looked terrible. Chad Dawson, Bird, RJJ, DLH (especially v Pac) are the most famous examples of fighters losing the fight before stepping in the ring. GGG (154-168lbs) can't do this and should never have implied he could. Stupid move.
