But we never use the term "clubbing" when we're talking about Joe Louis or Mike Tyson. No one ever says "Joe Louis clubs him to the canvas".
I've always taken the term clubbing to mean winding up with poor technique, as opposed to straight, clean punches and textbook hooks. Anyone can generate power by clubbing, but you leave yourself open, don't utilize reach, and won't get past tight defenses. I heard one reporter say, for example, that Carnera could club a guy to death if he got him in a corner, but he lacked true power.
I think it applies more to his first career when he was throwing winging lefts and rights. He did some of that in his comeback but by then he was throwing straighter punches. Tim Witherspoon sometimes did a bit of clubbing too
Foreman was not a sharp puncher with snap .. he was simply , possibly the strongest natural fighter the ever lived .. he fought like a strong guy and not a natural fighter that terrific jab aside ...
Because his punch didn't have as much snap or speed as more fluid combination punchers such as Louis, Tyson, etc. the body mechanics were completely different. You get hurt either way, but the feeling is different. He relied on his sheer physicality and arm strength to do the damage and his fists were the wrecking balls delivering the power. The last time I fought a "clubbing" type of puncher was a 5'9 guy who was built like a refrigerator. Very wide, big shoulders, big hands, stocky build. Probably 230-240 lbs. He just swung his arms as hard as he could with brute force. Didn't really have proper torque or technique, but his punches still hurt and had a numbing effect.
What made Foreman so deadly is that he was a clubbing puncher, but had legitimate power, used his reach, and had a sick jab
People have to keep in mind that Foreman had a very short , highly successful amateur career based on his natural size and strength and power and chin ... he succeeded but was very raw .. he never learned to throw straight punches , slightly looping or curving all his shots aside from a fantastic , jack hammer jab that could break bones . The limitations of his first career were underpinned by emotional immaturity. Foreman was a very smart man. He was an avid reader for pleasure when most of his contemporaries could hardly read at all or write their names on a contract. However he was an emotional novice and it showed in how he behaved in default moments when things did not go his way such as Zaire, Toronto and San Juan. He grew up in the ten years between careers ( a period filled with some fascinating stories ) and the second career fighter was sum total better than the first , diminished raw skills and all ... This is a terrific story of Foreman post Zaire and first retirement for some that may be curious .. https://vault.si.com/vault/1984/10/08/after-fall
