How many times Jhonny Gonzalez was leading a fight then suddenly got KO'ed?

[ElTerribleMorales]

OK I'll give you a pass about his glass body but how about his glass chin??
.

how does he have a glass chin? he took bombs from Vazquez, who is one of the biggest punchers in his weight class, after 10 rounds, Penalosa beat Jhonny mainly due to his inability to make the weight anymore, Nishioka has 21 of his 34 wins coming by KO, so he's hardly a feather fisted fighter, and hey it's not like he was hurt by a dude two weight classes lower than him

Jhonny already has a total of 7 losses and his last 3 were big disappointments since he's doing very good in those fights then suddenly he got KO'ed... 2 of those KOs were in the chin (1 in the body) that makes his chin questionable...
.

yea and Glen Johnson has how many losses? yet he's still a force today
