yeah i am pretty sure it is very rare if not impossible to have an upset in mma today
only when random matches are made can a true upset happen ala tourneys or
random such as joe lauzon filling in then getting the win over jens
random such as saying the winner of "the ultimate fighter: hasbeens" gets to fight for the title
but fights such as fighter a vs fighter b are never really upsets, because they make those fights knowing each fighter has a decent chance
bj beating matt is not an upset, bj is a legend in his own right, and getting beat by him is neither an upset or a mark against him
randy beating chuck is an upset???? i don't think so....
