I used to buy the 84" but not anymore. Ali's wingspan was only 78-79" Liston may be 79-80" at the most which is still very freakish for his height, roughly equal to Big Cat or a lil shorter.
What an 84 inch wing span on a 6'1-6'2 man really looks like:
Jerry "Arms to his Damn Knees" West. Wore the same sleeve size as 7'2" team mate Wilt Chamberlain. Big hands and broad shoulders too. Totally freakish even in basketball.
