Would anyone count Rey Mysterio? with him being outside the WWE bubble and hitting a ton of places and a variety of opponents along with his experience I'd say I'd throw him in.
Rey's a tough one as his post-WWE run probably doesn't net him too many points for this discussion. Has some bangers in Lucha Underground but not enough where he's a top 10 or so wrestler for the past few years. I don't think that's going to be improving anytime soon.
Cena should probably be mentioned but hard for me to realistically think that someone that has not been the best wrestler, or in the top 3, in his company for a single year makes it sort of hard to justify in my eyes. Granted, someone might say his 2011 deserves that rub.
Sekimoto hasn't been included cause he's not that good.
