And you believe a word hearn says?
So explain the way Joshua was before the fight and up until the 3rd round when he got caught on the temple?
Not trying to make excuses for him, he got beat... but do you seriously think from the very start it was the same Joshua we have always seen?
I never believe what anybody says. As a follower of horse racing and boxing you pretty quickly learn to ignore quotes and reputations and the like, you learn to concentrate on facts and what your eyes tell you. If you don't do that you'd go broke pretty quickly backing racehorses.
To answer your question yes it was the same Joshua as usual. Joshua is what Joshua is. He's a big man, strong and athletic with a powerful punch and a good level of boxing ability. What he doesn't have is upper body movement, a particularly strong chin and despite his athleticism he doesn't have the fastest hands neither is he exceptionally mobile in the ring.
Joshua's best win was probably against Dillian Whyte in hindsight. When he beat Klitschko (a fight that could've gone either way) Klitschko was 42 years old and clearly on the slide, yet that fight was competitive. Joshua struggled in the early rounds against Alexander Povetkin, a 39 year old who has been been banned for using performance enhancing drugs and since returning from that ban isn't the same fighter. It took him five rounds to get rid of David Price who has one of the worst chins in boxing above domestic level. Joshua's other notable win was against Joseph Parker, a clear yet uninspiring points decision.
Now people expected Joshua to easily beat Andy Ruiz but lets look properly at Ruiz's record.
Before the Joshua fight Ruiz had been beaten once in 32 professional fights. That one defeat came in 2016, a dubious points reversal against Joseph Parker. At the time Parker was an unbeaten, hyped up fighter that was always likely to get the benefit of the doubt if it came to scorecards. I watched that fight and I had Ruiz a clear winner, two or three rounds but the boxing world was talking of Joshua v Parker down the line and Parker got the decision. That decision should've gone Ruiz's way. Had it done he'd have been unbeaten in 32 pro fights to add to 105 wins as an amateur. This guy is a good fighter, underestimated by casual observers because he doesn't look the part. For a heavyweight he is comparatively small and he's fat. But he can fight.
Some of us have always said when Joshua comes up against a top fighter that can move or that can take his power and return it he's going to have a tough night. It came as no surprise that Ruiz with fast hands gave Joshua trouble.
If you'd asked me before the fight who would win this I'd have said probably Joshua on points but I'd have said it was a 60 / 40 fight because Joshua is the best fighter Ruiz has faced. Some people claiming this result is the biggest shock of the century are talking absolute rubbish. Jeff Horn beating Manny Pacquiao (just to give one obvious example) was a way, way, way bigger upset than this ever was. This result wasn't even a shock if you follow boxing closely. Maybe a surprise yes, because Joshua was the champion but some huge shock, no way.
Joshua was always likely to be troubled by hand speed. Saturday was not the first time, he was stopped as an amateur by a shorter, quick opponent:
