Brock Lesnar has been exposed as being completely overrated by Cain.

-He beat an old Heath Herring and couldn't even finish him after shattering his eye.

-He beat an old and natural LHW in Randy Couture, and needed an illegal back of the head blow to do it.

-He beat Frank Mir, which in hindsight is not too impressive.  Carwin did it better, as did Brandon Vera.

-He beat Carwin only due to Carwin gassing.  Carwin destroyed him for the entire first round.

There, that is the extent of Brock's resume in the UFC as far as wins go.  Nothing too impressive.  People just got wrapped up in his freakish size and speed.

*phew* - Now that we have those out of the way, anybody else who wishes to employ the "revisionist history" that is so popular in MMA will have to think of new arguments.
