I didn't include Povetkin and Fury in this list since they doesn't carry as much blubber as the guys who are mentioned is this poll.
The best boxer despite being fat. If it was in terms of impressive fatness, I'd include only two names - Dustin Nichols and Chauncy Welliver.
Jarrell Miller is by far the best fatman heavyweight, Gorman is the most talented but he isn't really that fat.
Diillan Whyte in his last fight was a bit of a chunkster. But if he's not on the list i'd give the nod to a motivated Andy Ruiz who is skilled and has great hand speed.
For a 300lb man, yes. Dude is a freaking beast if you think about just how ridiculously heavy he is. And he moves quite well.
