another golden egg
I want to say kid yamamoto. But injuries played a big part so even though it's somewhat understandable it's hard watching him lose now when you think of how dominant he used to be. 
Huerta. Dude had a great roll in the UFC, one win away from a title shot...
Leaves, goes to smaller promotions and has a terrible ride. I don't even know when he's fighting anymore, just log on here each day and then I see him getting his head kicked off.
Also, he's still quite young so that's even more surprising.

blew up over night lolol
Tyson,is a good one.......he was widely regarded as a future multi,time champion ir contender and he really got lost in the shuffle.......
Jens
Bob sapp
Hardy
Dave terell
Heath 
Joe daddy. Never been the same since he was destroyed by bj
Filho and Kang surprised me. They each have had a lot to deal with - chemical dependency and the loss of a loved one, respectively.
Nino Schembri?
Homnick
Bones Jones once he goes to heavyweight
Rick Story... Honestly thought I was looking at the answer to GSP and the next champ a few fights ago.
MacGowan - As difficult as it is for me to say it, Crocop's UFC career was quite a shocking disappointment.
Todd duffee
nipperusa - Todd duffeeGood one
NarlyPersianDude - LOL at the ignorant op and the inaccurate perspective. Who the fuck would call Fedor's career a fail, he lost 3 fights, his entire career, he already had a decade long run as not just top heavy, but p4p number 1. When Michael Jordan came back with the Wizards and could not even win playoff series, no one called his career a fail, he already did it, and you can take away great deeds.Career FALL
The question by the op, is okay, but putting Fedor up as an answer, just shows alarming ignorance. FoSho
Vemola.
Was throat slashing at opponents and shit beating them till he came to the UFC and hasn't really been at all as effective since and dropped 2 weight classes.

Fucking stupid fack!
I win by saying David Terrell.
/thread. Goodnight.
Chuck.
I said Rampage would beat him again, but I did not think his career would go downhill so rapidly.
The shocking thing about Fedor's loss is that it was to a grappler! If he lost via getting KO, due to his sloppy punching style, would make perfect sense.
Mayhem
itswhitty - A lot of people seem to be confusing the word "fall" for "fail" -- the OP refers to the latter.
Anyway, I'd throw Sokoudjou's name in the hat. He never really had a dominant period, so he might actually be closer to fail than fall, but damn... It seemed like his win over Rogerio might have been a fluke, but when he took out Arona it looked like he might have been the real deal. He still has occasional flashes of brilliance even in his losses, and it seems like he has the physical tools it takes to be a better fighter, but he just folds too easily. Maybe he surged too high too fast, or maybe his head just wasn't quite right. Either way, it's too bad.
FAIL.
