Regardless of whether or not some TMA's have "always" had some locks, clinch, sweep, throw, and ground within them - in addition to striking and kicking...it's undeniable by this point that MMA's and the VENUES through which they proceed have had an enormous impact on TMA's...
if for no other reason than the intense competition (and real, no BS contact) has made it crystal clear that the emphasis on striking/kicking - to the neglect of the other phases of fighting (clinch and ground)...
doesn't cut it anymore.
