As far as least profitable goes there have been so many. Heavyexplosion cards from C.Kushner were worse and probably drew less revenue. In the early days of DTV small PPV's were on often, problem was few watched them. Fighters like Jones Jr. and Holyfield know they can rely on their fans to at least make more money than they would fighting on ESPN2 or Fox's BDS. One problem is that less people watch.
