He already was, to anyone who actually observes. Not a single real loss or chink in he armor yet. No other fighter can claim that, let alone a guy who's already almost cleaned out the division.
GSP has lost and been battered in his last fight. Silva just got the crap beat out of him. Again. It's not the first time it happened. Jones has barely been scratched.
Cue "oh but jones needs to fight SSSHWs and trucks and tanks, you know, cos, long arms. Him fighting legally in a division where he makes weight is unfair, all the other champs never cut a single pound... they drink up on cream soda before every fight to make weight".
And this is coming from a bigger fan of GSP than Jones.
