Boxing fans today are the same as the boxing fans of yesteryear. Nothing has changed. Many boxing fans have always wanted action fights and action fighters, this crosses all eras of the sport. Rigondeaux would still stink out the joint during the golden age of boxing, which would be the 20s to 50s and would not attract fans. The boxing fans have never changed. Here's a documented example:

Boxing's biggest current attraction is a roughneck middleweight from Manhattan's tough Mulberry Street. Rocco ("Rocky") Graziano packed them in at Madison Square Garden last week for what fans thought would be his sixth straight knockout, a new Garden record. He fooled himself and the fans by winning on points from ex-Sailor Sonny Home.

He had little boxing ability but possessed the punching power, chin, and most important of all the all out action to be a marquee attraction. Rocky Graziano was the Provodnikov of his day. Want another example? The great Jack Dempsey whom even boxing writers back then described as an all out brawler sold out stadiums and became the most famous athlete in the world, he even surpassed Babe Ruth in terms of popularity during the roaring 20s. How about another example? The very 1st heavyweight champion, John L. Sullivan aka the Boston Strong Boy, was described as a brawler and mauler who brought out the masses because he was exciting, while Gentleman Jim Corbett who outboxed and ko John L. Sullivan was described as boring and not as exciting as Sullivan. Sounds familiar?

The boxing fans have never changed, we have always wanted the action fighter and action fights. A Rigondeaux would not be fighting in Madison Square Garden and selling it out even during the Golden Age of boxing, that arena was only reserved for the marquee attractions.
