5 best Brock Lesnar UFC fights

#3 Randy Couture - UFC 91 (November 15, 2008)

Brock Lesnar smashes the champion with a big time left hand

Many scoffed when Brock Lesnar was named the number one contender to the UFC Heavyweight Championship versus three time titleholder, Randy Couture with a record of 1-1 inside the Octagon.

Regardless of whether he deserved the shot or not, Lesnar was every bit the match for the Hall of Famer, Couture.

Lesnar, unsurprisingly overpowered Couture, driving him into the fence and took him down, unleashing some heavy ground and pound blows. Couture withstood the assault and looked to take the initiative in the guard.

Couture tried to find space to work a submission but the sheer size of Lesnar prevented him from being able to do so.

When the fight got standing, it was all Lesnar. The "Beast" landed a big time right hand that knocked Couture down. Lesnar was the Heavyweight Champion of the world.
