"No" That punch was anything but lucky ! Jackson biggest weakness was his belief in his punching power. He believed so much in his punching power that he would wait look for the perfect moment to land his one punch KO power. So it was not uncommon for Jackson to be behind on point against quick fighter (Norris) Gram made the mistake of giving Jackson the perfect opportunity to land that punch buy moving in with his Hand down to his side while attacking. Gram made a huge mistake and paid for it. Not lucky at all.
How about RJJ vs Tarver. RJJ won the first fight. It was close but I do think he won it on the cards Then the 2nd fight Tarver lands a punch right on the button that Rjj never saw coming. Then the 3rd went 12 with only a few moments of excitement.
the punch because youve thrown it thousand of time in the gym andif the opponent fall that mean your fist were alive its no luck no matter how far behind you are on points
luck it may be because spirit fickle even when thrown thousands of punch sometime close eyes and wing big fall maker land sleep many moons.
