Of course i have an opinion, but like others, it is wargely effected by my personal feelings about some sports. Without having the backstage information about profits, attendancies, on air viewership etc. any suggestion i make will be purely on my fan's perspective. Like i've said in the sailing thread i have no idea why this sport needs 10 set of medals, as i don't know the differences between the Fin, RX, Lazer etc. classes and why all of them should be in the Olympics. But after me, another 5 people will enjoy sailing and know everything about it. Same with taekwondo, for me it was such boredom to watch even the little that i did in Rio. But others may like it more than other combat sports like wrestling/judo/fencing etc.
Some people say ditch mens football because it is a junior competition, but it had the best attendance in Rio and i'm fairly sure it had bigger TV ratings than 70% of other sports. It is football, you can't just get rid of it.
One thing that should happen for me is increasing the volleyball / basketball field to 16 teams. Those two team sports are too popular to have only 12 teams and with 16 days it is possible to support 16 teams and still keep the 6 matches per day schedule.
Also, like i've said in the 2020 thread i hate the double standards the IOC has. They have blabbered for some time, that the Games shouldn't become too big, and "we will control the number of athletes and categories" and put rigorous qualifying standards and whatnot and then go ahead and bring in new sports that no one really wants or have absolutely no international competition to support an Olympic inclusion. If there is one thing a would suggest, it's stop cutting down traditional Olympic events, either entirely from the programm or by stripping their participation to 10-15 people in discipline / categorie...
