I think the fight is worth buying. As a GGG fan I think time is against him. I have GGG up in the series 1-0-1, but Canelo played the game and waited until GGG started to age. "Tainted" meat to push back the the 2nd fight then waiting this long for the 3rd really put all the cards in Canelo's hands. GGG needs to box, which his skill never seems to get talked about since he is such a destroyer and with his granite chin puts that skill to the side in order to just break people down. To beat Canelo he will need to be a little more cautious and tighten up the defense.
Sorry, but Fury is definitely highly skilled. He and Usyk are easily the most skilled boxers in HW and it's not even close. Too bad Fury was pushing Usyk for a fight by the end of 2022. Now we will get Fury/Joshua, which should be good I give Fury the edge though fairly easily. Usyk will likely take a fight in early 2023, hearing murmurs of it being against Wilder if he can get by Helenius, which would put a Fury/Usyk showdown well in to mid 2023 if it does happen.
Spence/Crawford is the fight to see. Hopefully they promote it well because even casual fans will be impressed with that. I think Spence is slipping and sounds a bit punch drunk recently with all his accidents and career mileage he may be at the end.
