This is the first in a series of posts I will be doing on game changers in MMA history.
Starting in the heavyweight division, I point to Brock Lesnar.
Love him or hate him, Lesnar’s arrival to the MMA scene changed the face of the division forever.
Despite just 7 pro fights in his career, you can clearly see a difference between how the division works now compared to how it worked when he first arrived.
Lesnar first appeared in MMA in 2007 and made his UFC debut in early 2008.
At the time, the heavyweight division had been run by the likes of Tim Sylvia and Andrei Arlovski, two predominant strikers.
Then came Randy Couture, a man who now can’t even fight at heavyweight due to the size differential. Couture was the heavyweight champion when Lesnar broke into the octagon.
When Lesnar showed up, everyone paid attention. Not only did it seem like a gimmick that a pro wrestler would move into MMA and into the UFC, but his shear size was hard to ignore.

The next marquee heavyweight bout has been set with Cain Velasquez defending his title against No. 1 contender, Junior dos Santos.
