I think people need to understand the strategy behind holding, and then can see what an unfair advantage it is . Most referees say very little. Thus the Tall fighter who uses this Manny type stradigy has already won the fight.
example
The short fighter has to work his ass off to get on the in the inside , the tall fighter then ties up. The average ref steps in and breaks them apart instantly leaving the short fighter miles away from his target all over again with no real chance to do anything . Hence the unfair advantage. This goes on until the short fighter is reduced to lunging into a big shot in which he is knocked down or out or he loses a decision . Never given a fair chance to win the fight.

Now with Nady as referee. that would not be allowed to happen. As Nady would inform both fighters that holding is an infraction of the rules and regulations of boxing and won’t be tolerated at all, thus the short fighter has an equal chance to win as he works his way in ,he can now fight on the inside and has the opportunity to do his work , the Tall fighter has to adjust and box his way out , rather then hold his way out. Giving both fighters an equal opportunity to win the fight. Its that simple, and that’s why the holding rule needs to be vigorously enforced. both guys need a fair chance to win !
