10. Royce Gracie
Firstly before you bite my head off, let me explain myself. I have found that back in the early days of the UFC, Royce Gracie was both loved by knowledgeable MMA fans who appreciated his effective jiu-jitsu, but he was also hated by the larger percentage of UFC fans who didn't know anything about MMA and just wanted to see two people punch each other for as long as possible.
Also after doing research into the matter I have found some modern day MMA fans accusing Royce of being cocky and of not letting submissions go even after the person has tapped, although we do see this from a lot of fighters who like to make sure that the referee knows the opponent has tapped, after watching some of Royce's fights he seems to hold on because of sheer anger rather than referee incompetence.
9. Bobby Southworth
I assure you this is all my idea. I absolutely hated Bobby Southworth on the first Ultimate Fighter, his antics in the house (mostly towards Chris Leben) and his disrespect for Dana White both led to him being the fighter I absolutely despise.
Firstly, I have no respect for a fighter that makes whines as much as he did, but add that to call Leben a fatherless b**** just takes the cake. He was the only blemish on a season of the Ultimate Fighter, which I liked every other fighter.
8. Karo Parisyan
Karo is arguably the best judo practitioner in the UFC and has had some amazing fights, the fight against Diego Sanchez comes to mind, but he also has an excuse for everything.
For example, in the Sanchez fight, he claimed he had been poked in the eye, when he actually broke his orbital bone and you could see that he went down not because of a poke to the eye but due to injury.
Also, mess ups like his unique concoction of painkillers that got him suspended for nine months lead to him being seriously disliked.
7. Diego Sanchez
The Ultimate Fighter Season One middleweight winner deserves some respect for some awesome fights and for some awesome knockouts. But there is one thing that gets under my skin, he treats every fighter he faces like they are enemies rather than just competitors, although this added intensity can lead to a better fight, Sanchez-Guida for example.
It does get tiring after a while and screaming 'YES' when he walks into the octagon is more confusing than it is funny and it is funny.
6. Diaz Brothers
Much like Diego Sanchez, the Diaz brothers are here because they take every fight like their opponent has killed their parents, and they don't seem to have any respect for their fellow competitors, leading them to be widely hated.
5. Tim Sylvia
One name that just kept coming up while I was doing my research, the 6'8" giant is truly hated by most UFC fans.
Mainly because he is one of the most appalling UFC champions of all time, he was champion when the UFC heavyweight division was stagnant and when a middle aged Randy Couture decided to return he was thoroughly beaten by the older, smaller man. Also the fact that he has no ground game doesn't help.
4. Michael Bisping
A name that kept coming up, especially after his knockout loss to Dan Henderson, Michael Bisping is often booed at UFC events, mainly because of him hailing from the UK but in UK UFC events its the complete opposite with him being hailed as the one true spark in UK MMA.
But coming from the UK myself I dislike Bisping, I agree that he has been given easy fights by the UFC and UK events have suffered from it. Bisping-Leben, who would pay for that PPV, the single worst event in UFC history.
3. BJ Penn
Currently instead of focusing on a tough contender, Kenny Florian, BJ is focusing on GSP and the rematch that I'm sure every MMA fan wants to see as much as Franklin-Hendo 2.
BJ is not entitled to fight GSP again, the current record against GSP is 0-2 so not really any point in having another match. I'm hoping BJ goes up to welterweight and is beaten by someone other than GSP so he realises he belongs in the lightweight division.
2. Tito Ortiz
The Huntington Beach Bad Boy who folds like a wet paper towel against any stiff opponents. Tito thinks he is great but doesn't realise he is far from it, he has been outclassed by Chuck Liddel, Randy Couture, Lyoto Machida and Chuck Liddel again.
His arrogance got on the nerves of the UFC, mainly Dana White, for then challenged him to a fight which Tito accepted but later backed down from. What kind of world class fighter would be scared to fight Dana White?
1. Brock Lesnar
Although Brock may not have had as much abuse as some of the other people on this list, considering the amount of time he has been in the UFC, he has had more than anyone.
Brock has had to endure countless experts counting him out, an embarrassing loss to Frank Mir resulting in more abuse from experts. And even when he win he still gets booed, although his reaction to the booing wasn't exactly the most gentlemanly, giving the whole crowd the middle finger, not good.
Personally, I love Brock and I was on the floor laughing when he had a rant at Mir and the crowd, but apparently it rubbed a lot of people the wrong way, but I just couldn't stop laughing.
So there it is, if you would like to point out anyone I might have missed or dispute the order please feel free to comment.
