Here are the reasons I don't think it should be an Olympic sport
1) The safety issue. There are so many safety issues that need to be addressed in MMA. This is more relevant to the striking part of the match. Take Olympic boxing for example. Head gear is mandatory and the gloves are most likely the biggest that can be worn. I just don't see MMA making it to the Olympics in its current form.
In a best case scenario, I would think that in addition to the current rules I would predict the following changes/additions:
a) no elbows or knees
b) shin pads must be worn
c) headgear must be worn
d) gloves might be bigger
e) shorter and/or fewer rounds - probably lots of decisions
f) a new point system would have to be implemented to better score fights that end in a decision
g) like judo, wrestling and other combat sports in the Olympics, an MMA event will certainly have to be tournament style, which alone can cause problems with fighter safety and even sanction rules (i.e. you can't twice in a day)
2) There is no need for it. The UFC alone has at least one show a month. What would a potentially watered down MMA tournament, once every 4 years give us that we didn't have already? Not much IMO. sure there is more international exposure, but do you think the American television stations will be televising MMA fights when swimming, track and field, etc are their bread and butter? Heck, I want to watch more judo and wrestling and can't even do that as it is.
3) There are already too many events in the summer Olympics. Take away 20% of what is there and I might consider removing this point from my list of reasons.
