You mean juiced to the gills Belfort. Outside of that one loss Rockhold has beaten plenty of top quality opponents in his last half a dozen fights.
He has beaten "good veteran" fighters. I would be hesitant to say they were top quality.
Keith Jardine (really?

)
Tim Kennedy
Costas Philippou
Tim Boetsch
Michael Bisping
I will give him credit where it is due, he looked great against Machida, and he has won the fights against good competition.
But we are now talking about the Elite category of fighters. Weidman, Jacare, and Anderson Silva etc....
Rockhold is 1-1 recently against "elite" competition. He will get his chance.
