9. Alistair Overeem Vs. Jairzinho Rozenstruik (UFC On ESPN 7)
As you're more than aware of at this point, knockouts inside of the Octagon can come out of nowhere and leave a contender seemingly still in with a chance of victory blown to smithereens.
That's the position that UFC legend Alistair Overeem found himself in when he took on the undefeated Heavyweight Jairzinho Rozenstruik at UFC DC.
Overeem looked good in the early stages of the bout and managed to take down Rozenstruik, before controlling his rival on the ground. The Dutchman even threw a few bombs which connected flush with Bigi Boy, though his opponent seemed to take each shot in his stride.
After continually attempting to put away the immovable object in front of him, Overeem grew frustrated towards the end of the fight and paid the price in the closing stages.
Detaching Overeem's lip from his face, Rozenstruik capitalised on his exhausted foe's state and caught The Demolition Man on the retreat with a devastating right with just four seconds remaining in the five round fight.
This engaging collision between two of the baddest Heavyweights in the UFC gave us a fantastic performance from an unfortunate veteran and a game-changing knockout from an undefeated rising star in the company. That's why it makes the cut as one of the most underrated clashes of the year... that and anyone who can rearrange your face like Rozenstruik definitely deserves your respect and attention.
