A top 10 is never a clinical science. Never. There is always place to interpretation and there are many factors to take in consideration? Does GGG deserve the prime spot? Based on the fact that he never backs off a top fight, that most folks are scared of him and that he just bulldozer his opponents (save from Jacob who gave him a run for his money), there are some good arguments to justify that he does. That wouldn't be abusal to put him in second or third spot though, depends of the factors that one favor and once again, it's not a clean cut science and it is sometimes difficult to determine which factor is more important than another given one. Even though we could argue that X or Y would deserve better the first spot, it would always be by a small margin and in that respect, it is not a "nonsense" to think that GGG could deserve it.
