I think it's quite the opposite, GSP has seemed more human with every year (blowing out his knee, nearly get finished by Condit) while Jones hasn't been challenged once yet in a few years of fighting in the UFC. If anyone seems invincible it's bones, silva, aldo and jds
How many rounds has GSP lost in the last 4 years? Now count many his has lost when you don't include a fight with an eye poke.
Jon Jones hasn't even been around that long.
