Do you agree with GMS academy member Will Rooney - here he ranks the top 10 heavyweights in MMA.
Check out the list below...
1. Cain Velasquez
His latest victory in his trilogy against Junior Dos Santos has all but sealed his place as the best Heavyweight on the planet.
In every single one of his fights except his loss to JDS, Velasquez has looked unstoppable, beating the likes of Brock Lesnar, Antonio Silva (twice) and Antonio Rodrigo Noguiera.
It looks like Fabricio Werdum is up for Cain who could cause him problems on the mat if it goes there.
2. Daniel Cormier
A training partner to Cain Velasquez - which is stopping him fight for the UFC title. He holds the only perfect MMA record in the division at 13-0.
Cormier has one of the best wrestling pedigrees in the sport and in his last fight against Roy Nelson he looked impressive again.
He literally had 'Big Country' wherever he wants. He came into that fight at 224lbs and is expected to fight at Light Heavyweight next time.
3. Junior Dos Santos
Just because he has lost to Cain Velasquez twice doesn't mean he isn't near the top of the pile anymore.
He showed the heart of a champion in his latest loss to Cain and was very close to stopping the fight more than once. JDS has looked unstoppable against everyone else bar Velasquez and unfortunately for him, while he is around its unlikely he'll regain the top position.
4. Fabricio Werdum
Werdum has undergone a resurgence since rejoining the UFC ranks. He's 3-0 and in his last fight became just the second person to tap out veteran Antonio Rogrigo Noguirea.
That victory granted him a shot at the title and providing he stays fit, he will fight in 2014 against Velasquez.
5. Antonio Silva
He fought for the UFC Heavyweight title however was unsuccessful against Velasquez.
However before that, he KO'd both Travis Browne and Alistair Overeem very impressively.
'Big Foot' is unlikely to get another shot at the title soon but he meets Mark Hunt in December - that could be a highly entertaining bout.
6. Travis Browne
The dark horse of the division, Browne posts a very impressive 15-1-1.
His only loss to Antonio Silva came freakishly after he tore his hamstring. He holds plenty of power, winning the KO of the Night award three times including his last fight, when he KO'd kick boxer Alistair Overeem with a very impressive front kick.
7. Josh Barnett
He's been a top Heavyweight outside of the UFC for years however Barnett is back among the best.
'Baby Face' was among the best when fighting in PRIDE and still is now. He still has it, knocking out Frank Mir via knee in his comeback under the Zuffa banner.
A fight with Travis Browne could see him move closer to a title shot.
8. Alistair Overeem
Overeem's kickboxing is the best in the UFC Heavyweight division.
In his debut against Brock Lesnar, he looked unstoppable and a serious threat for the title.
However since then, he has lost his two fights by KO and his career in jeopardy. He meets Frank Mir in a must win fight next.
9. Frank Mir
Mir is in the same ship as Overeem. He's 0-3 in his last three fights, and was seriously beat down by both JDS and Josh Barnett.
It's sink or swim in his next fight against Overeem on February 1.
10. Stipe Miocic
Miocic has been outstanding in all his UFC fights. Even in his TKO loss to Stefan Struve he was winning the fight before getting caught.
Miocic's résumé is seriously impressive - an NCAA Div 1 wrestler, and a golden gloves boxer.
His latest dominant victory against veteran Roy Nelson was his best display of his career and I look forward to his fight with whoever he is matched with next.
