Wow, that would be so amazing. First of all, Eddie does more nogi, and trains with more top nogi guys. I would assume Eddie is more comfortable than Royler with other non-traditional, non TPJJ positions as well, such as 50/50, deep-half, etc. Another thing to consider is that Royler is now 45 years old. Eddie (sorry to call out your age man, but it's on wikipedia so I figure it's no secret) is 5 years younger. The difference is much bigger now than it was 7 years ago. I think Eddie is probably in way better relative shape as well, if you compare current conditioning levels to the difference in conditioning between them in 2003. Furthermore, I don't see Royler importing a bunch of TPJJ guys to train for Eddie (as he should, if anyone would go). He is too confident in his own game to do that. In other words, while Royler is no easy fight for anybody, I think everything favors Eddie in a match like this. That being said, if this happens, you better train your ass off Eddie, because after 2003, you know he's going to. Good luck!
