Yes Usyk can hurt AJ. But he should be looking for angles and turning him instead of slugging. Slugging is Joshua's area. If AJ gets tired - and he will - then the KO will come.
That's the key for me. What's in AJ's tank. I don't think he can box Usyk like he did Ruiz in the rematch. If he trys to go through Usyk and doesn't get him outta there, AJ is done. He will exhaust himself going for the stoppage. His recovery is terrible. I just don't see AJ winning this fight. Less stamina + Less skills = AJ looses.
The books have Usyk at +230. I put a bill on him because for me those odds are too good to pass up. I think this is a 50/50 fight.
