I'm always excited for a Fedor fight, but his previous retirement was preceeded by three of the easiest fights he could line up. He took out dinosaur Rizzo, Monson and beyond shot Sylvia.
There's a reason he didn't try to transition to UFC before retiring. He wanted to go out on some easy wins and he did that.
Now that he's supposedly signed with the UFC we'll see if he's back to old form or not. I firmly believe that an in shape and focused Fedor is still a very real threat to anyone in the UFC.
If he comes back in Strikeforce shape he's going to get mauled.
