IMO, this is a smart move on the part of Werdum for a few reasons. If Cain happens to beat JDS in their rematch, Werdum would be next in line for the shot given that I don't believe Cormier and Cain will fight each other and if JDS wins, they have a built in rematch that I think can tell a pretty great story. I also think that they'll make Overeem take a fight before he gets a title shot since he pissed dirty, probably against Bigfoot. I wouldn't be surprised if JDS or Cain drops out of their title fight that Werdum gets the call up, while I think they'll want to establish Cormier's name against a Mir or Nog.
Werdum has been playing a hot hand since he left ZUFFA and I think his recent string of victories over Nelson and Russow on PPVs makes him more marketable.
