There are many more questionable decisions than those listed below. These are just my top 5 most controversial. Please feel free to add your most controversial decision (if not listed in my poll) below in the comments. I have quite a few more, including smaller shows, but I chose to go with these 5 because they are probably the most well known and most controversial. I personally think that Bas Rutten getting the nod (for the UFC Heavyweight title) against Randleman at UFC 20 was the most corrupt and awful decision ever. What do you think was the worst decision in UFC history? Enjoy! I look forward to your thoughts!
