Interesting.

I always thought there wasn't much of a size difference between them.

Ironically, while GGG has little weight to lose (so he will go down steadily and retain strength and stamina), it may be Brooke who has to crash weight. That's never good as he will lose it too fast, so muscle as well as fat will be burnt off.

Kell has a history of fucking his training and weight up. So far he has got away with it - just, in the case of Carson Jones - but he's not facing a Jones now!
