As far as winning the fight they are not. That 115-113 card demonstrates that his chances of winning on the cards are decent even though his chances of winning the bout are close to non existant.
I like both, but it's always exciting with redemption and seeing someone make adjustments to get by a formidable opponent, so Joshua for me too. Won't be sad if Usyk wins, which I think he will, though. The main thing is that the winner faces Fury.
I think AJ has a chance, and i enjoy rooting for the underdog. But if i'm being honest with myself, I think Usyk has the greater boxing IQ and will come out ahead.
Usyk is still the underdog in the sense that the crowd, referee and judges will all be against him. Assuming the fight is in the UK of course.
