His holes have been widening for a few fights now, Maidana out jabbing him for a couple rounds, had him blinking with a tweeked nose and damn near shouting in corner. I know..he 'choose' to fight that way. His accuracy is on another planet but half the time it was going backwards or moving into the next prevent. Berto landed some ugly clumsy left hooks that he should not have. Everyone waits for that grow old over night fight or surprise, we do it with all top guys. But its a slow erosion really, always happens. Too many top guys hang on showing more and more tough chin or counting on power as the ones coming up only grow stronger and have more to study on the subtle slippage of a fighter. Floyds power is his elusiveness, hand speed and reflex defense..not punching power and willingness or even ability to rely on chin. His timing is great..hope he stays retired!
