That element of fan, the Wrastling Truck types, is necessary for the growth of the sport, one can hope that they graduate beyond the stage of only appreciating knockouts, slams and GNP to appreciate the tactical finessee that distinguishes MMA from kickboxing, fake wrestling and Tuffman contests.
It's a learning curve, some of us are further along, more will join us over time, some will never get it, they're at least good for contributing their $ to build a better sport by those in the know.
Along these lines and Bruce Lee and the variations of Kung Fu, these types and some that should know better fail to appreciate that boxing gloves nullify the precision strikes that these arts are built on for real combat, a boxer may Ko a Kungfu guy in the ring, in a barroom the Jeet Kune Do guy may knifehand the boxer's windpipe.
The evidence on Lee suggests, to me, that based on non movie clips and writings, that he was masterful and dangerous, unfortunately there does'nt appear to be much, if any, ring footage avaliable to assess his skill from, and if there is, hard again to judge his real fighting ability when eyestabs and the like are not permitted.
