Gamburyan's a quality opponent, don't hate on him. He KO'd Mike Brown faster than Aldo did, and since then he's only lost to Aldo (arguably the FW GOAT), Tyson Griffin (in a very close fight that could've been a draw, and not to mention Tyson Griffin, despite having on-and-off performances, has always had the potential to be a world-beater, and that night he was very much on), and Diego Nunes (one of the top contenders at FW).
It might be a strange matchup, just considering their recent fight history, but don't hate on Gamburyan cuz' of it. It would still be a good win for Mendes.
