I was disappointed in the GGG vs Canelo fight, GGG just didn't have enough in him to go at it for 12 rounds. He is my preferred fighter out of the two and definitely think he should have won the first and didn't lose the second so was really rooting for him this time around. Unfortunately, it wasn't meant to be as father time seems to have caught up with him, he came on strong during the second part of the fight but unfortunately, it was already too late.
In terms of Joshua, Fury, Wilder and Usyk, I think whoever wins each fight will meet each other again. I reckon it will end up with an Usyk vs Fury fight for all the belts, but I wouldn't completely count out Wilder, Usyk has yet to feel real power and if Wilder can catch him, I am not sure anyone but Fury can get back up.
When Joshua loses I think he would want to go out on a win and would take up a fight with Whyte as he could see himself being the winner there, but not even sure he could beat Whyte these days. I would want Whyte to win regardless, he has always said that Joshua was a fraud in his personality.
