I don;t think he looks tired from his feud recently. I just think that this feud with Sheamus is not that interesting. Partly becuase if you remember, the two wrestled in front of the infamous New Jersey crowd who trolled their entire match a few years ago.
Sheamus and Orton just don't have good chemistry and just don't have that good of matches together. I personally like Randy Orton and wish he would stay full-time but feud with someone like a Brock Lesnar or Kevin Owens or Cesaro. Lesnar is someone I would like to see Orton have a feud with but it looks like Lesnar is probably going to be feuding with Taker for the next few months or even up until Wrestlemania.
Surprised Rey Mysterio rumors about him thinking about returning to WWE because it sounded like he had some issues with him and WWE when he left. I would think he would be more intersted in Lucha Underground considering his Lucha background. I would liek to see him in Lucha Underground myself.
He would probably just come to WWE and be the veteran that puts over guys which is okay but Lucha Undergound is so much more excciting then WWE that I think Rey would like being there and fans wouuld love him. I don;t see him being a teacher or manager. Just does not really fit Rey Mysterio much.
He isn't a part time nor did he look tired.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
