Dude- Lesnar is a great athlete but so far to say he's been tested is absurd.
He's 4-1 and his wins came against a 76 year old Randy Coture who was outweighed by 80 pounds, an equally ancient Heath Herring that was clearly out of shape (Lesnar couldnt finish him either) and Frank Mir, who by anyones measurement is vastly overated and spent the whole fight on his back trying to finesse another cheap ass heel hook type submission victory. Everyone drank the Kool Aid when he finished the 48 year old Noguerra for the first time--- neglecting to mention Noguerra was suffering from like 3 different injuries and had like a 200 degree fever.
Brocks big and mean and a world class wrestler. However, thus far all he's shown hes been able to do is take naps on his ridiculously undersized opponents and throw hammer fists or hooks from the bottom.
Brock may develop into one of those elite guys down the road, but right now-- he isn't a pimple on Silva's, GSP's, Fedor's or Machida's asses IMO. He's just a gigantic hungry wrestler with a mean streak that is taking advantage of a shit poor joke of a heavyweight divison. The elite guys have fought the best of the best in their weight classes and dominated repeatedly.
Perhaps you were trying to be cute, but your age exaggerations were a bit ridiculous. Aren't you about 14 yourself? I guess everyone seems over 45 when your mommy still makes your lunch every day.
You are completely correct overall in that Brock is still largely unproven. You can't turn a guy into a legend after a whopping five professional fights.
