About 5-10%. He is old and slow. He has a puncher's chance like any heavyweight with decent power, but I doubt he'll be able to land anything before AJ lands on him.
Regardless of it being a ridiculous mismatch, you can bet your life Hearn will have the one way rematch clause in the contract.
Can't see it happening. Even a prime Helenius wouldn't cause an upset. He hasn't got that one punch KO power for a big guy to trouble AJ.
Before the Wilder KO, I'd give him a decent chance as he seemed in shape and confident after dispatching Blubber Pole. Not sure how much belief he has now. He's big, experienced, has some skills and has power, so it's possible he lands something and follows up. But hard to get any hopes up as there's a reason Hearn picked him as the lesser threat. Maybe they know some other things, injuries, sparring form etc. It's all carefully calculated. He definitely hits harder than Ruiz though, so anything can happen. Rob has his chance to end Hearn-J for good and become a forum legend.
I should think completely unlikely. But the boxing ring can be unpredictable. And I couldn't resist putting a fiver on Helenius winning in round 1 at 80/1.
I think he has a chance, a small one. Aj has been fighting pretty much the best available since his 12th-14th fight so he is a bit shop worn. There will be a fight where aj just doesn’t have heart for it anymore, & who would blame him, he’s rich and young he can just go retire and live a good life. Even if loses he still has a decent record.
There is always a chance however I can't see that there is a remote one of him beating Joshua. After a feeling out round, or two Joshua ends this one and probably doesn't ship much punishment at all in the process.
The chances are very small, Joshua will win even easier if he decides to go the distance, but after this fight Joshua will perhaps be more appreciated if he takes the risk and completely destroys Helenius.
About as likely as him taking a flush right hand from Joshua and staying conscious. So yeah 0% chance.
