We don't even need heavyweight superstars. Just a division with 4 or 5 guys who have "star" marketability. It can be any division. It's what made this sport so fucking compelling in the 80's as you had three or four divisions and each had various star fighters.
aside from the heavyweights boxing has plenty of talented fighters who could/should be stars, but those managing the sport just aren't making the kind of high risk fights that are needed to make stars......and in the rare cases that they do make a good fight, they fail to properly promote it.
mares, moreno, donaire, salido, gamboa, rigondeaux, broner, guerrero, pac, mayweather, marquez, cotto, ortiz, khan, garcia, alvarado, kirkland, alvarez, martinez, quillen, ward, dawson, froch, and dirrell are all great fighters that consistently entertain.......while lee, rios, chavez jr., maidana, lundy, angulo, russell jr., juanma, berto, peterson, alexander, pascal, lara, and jones might eventually prove, or redeem themselves.
