1st sentence is true, but that was what the whole of Usyk's game was supposed to look like: no power, gassed with the extra weight, so much less movement and awkwardness, but the only thing that hasn't come up with him is the power.
I don't agree with the second sentence, though. Joshua hit Usyk a lot, people seem to have not registered that, h also made adjustments in the middle rounds that caught Usyk off guard and he threw a really skillful, unsuspecting feinted uppercut to the body that made Usyk wince.
There has clearly been work put in to modify his game and just because it didn't work against Usyk - who is a masterful boxer as we all know - it doesn't mean the work never occurred.
