Ruiz was not relevant before he destroyed Joshua. He wasn't even going tpp get a shot against Joshua until they needed a late substitute.
Now he is relevant and Wilder has a full plate with Ortiiz and Fury.
Dariusz Michalczewski would not leave Germany and Roy Jones Jr was one the top p4p fighters in the world. Why should Jones have to go to Germany to chase him. Jones would have destroyed him like Tiozzo did.
Mayweather did what Mayweather does.
By making sure he has every advantage in a bout? Would have been interesting to see this fight five years ago when it should have happened.
