Nice try but Mike knows speed when he sees it. He had that attribute in spades. Dubois also credited Usyk's speed for the power that he generated. It's almost like a pattern is starting to emerge.
The fact is that Joshua is much rangier than Usyk. He enjoyed significant height & reach advantages. So did Fury and yet it didn't matter. Usyk was able to constantly close the gap, land his shots, and get out without being clipped. How? By having the hand speed to match his foot speed. Your feet & hands are supposed to be synchronized anyway unless you deliberately split your timing. He's fleet of foot which allows him to constantly beat his opponents to position and his swift hands allow him to actually capitalize. The more you know.
