Heres why the OP is complete fail.
GSP is 29
Silva is 36
When Silva was 29, what did his list of achievements look like, hmm? He was the cage rage MW champion.
He got flying scissor-ed in Pride.
Those are the most outstanding features of 29 year old Silvas fight career.
Meanwhile, at 29, GSP? ... need I go on?
lol. Utterly lol.
lol sorry but this truly is a sad argument, vitor was the UFC HW champ when he was 19! where was GSP in his career when he was 19??
