Building a fan ‘base in boxing is a different animal than in other sports. There is no central league office, with a cadre of press relations persons, helping propel the reputation of the “league” and the athletes who comprise said league into press and rooter prominence.
Boxing is a frontier sport, the barrier to entry is low, and that appeals to independent types. It’s every man and woman for themselves, at times, and so boxing often plays within a rules set that tracks alongside capitalism at its core. You get the deal you negotiate, not the one you “deserve.”
