Calm your tits, it means little to nothing. He always looked like that before every fight. Included Marquez 4. One thing is flailing the arms, another one is catching someone running away all night long.
Lol he doesn't throw combinations like that in the ring. How is that so hard to understand? His shadow boxing is much faster than his in ring performance because he's not getting full extension on his punches.
Super fast as usual. But, I hope he's practicing moving that head in rhythm with this hands and protecting that body. Because, Floyd is shooting straight for the target.
