The fight that needs to happen next is the rematch of Werdum vs JDS whether Werdum wins or loses his next fight against Nog. I think the first fight was a fluke win for JDS and Werdum got caught by the then unknown fighter and came in very unprepared. I definitely think Werdum wins the rematch and would favor him greatly in that fight. Werdum could tire JDS out spamming for take downs and use his improved striking. I think JDS would get very frustrated and Werdum gets that win and could very much end the fight by subbing JDS in round 2 or early round 3 as JDS gasses. That would be a great fight to see.
