Diaz KO'd a 20 year old Robbie, 12 years ago. Has no bearing on today.
Was outstruck by a LW BJ in the 1st round 33 - 20. BJ won that round on all cards. Then "BJ Gonna BJ" and gassed. An in-shape BJ outstrikes Diaz all night long. But we almost never see an in-shape BJ. BJ was outstruck much more by Frankie, a fighter who can make 135.
Shamrock retired nine years before fighting Diaz. When he did fight Nick he went into the cage with a broken rib and no real intent to win. He was a paid shill for the promotion he worked for, to try to make Diaz look like he could beat "Name" fighters. Seems to have worked, as many Shertards are convinced.
Was outstruck by Condit. Lost 4/5 rounds.
Was outstruck by Silva, a man nearly 40 years of age returning from the most horrific injury I've ever seen in the cage. Lost every round. Fought for a paycheck, obviously trying to avoid being KO'd. Showed real cowardice there. Silva's drugs had nothing to do with what happened inside the cage.
Was boxed up and lost to KJ, a middling LW fighter. Was getting boxed up again by this little fella until the size difference kicked in.
His signature win for his career is beating Daley, a 1 - 3 fighter in SF. Congrats.
The Fireball Kid is perhaps the most overrated fighter in MMA history, excluding Nick. Check out his record without all the bush league wins in 3rd rate Japanese promotions. What does GoGoing some LW 10 years ago have to do with who is the best WW striker currently?
