Sure, I would watch that rematch. Of course! But there are some small issues... Fedor would first have to fight someone a little higher ranked then Singh Jaideep, Pedro Rizzo, Satoshi Ishii and Jeff Monson. Those are the fights he won since he lost to Hendo back in SF. Even if he did win the last fights it's not like he fought anyone close to Werdum or Velasquez's rank lately.
And there is the issue that Fedor is not in the UFC, so how will he fight a UFC fighter? I do think Dana is crazy (smart
) enough to set it up, but I don't see it in the near future.
