Excellent Choices Shadow. I've held off commenting for the last three weeks so I can do them all together.
Edge: Edge, Edge is the man. He has been the best thing the WWE has had since his return in 2004, and his subsequent heel turn at the end of 2004 and beginning of 2005. The man consistently puts on match of the nights and steals the show.
Some people argue, oh, he only brings his A game in gimmick matches. You know why he gets all the great gimmick matches? Because he delivers each and every time. His regular one on one matches are great as well. Whatever the WWE asks him to do, he delivers. His mic work is untouchable in the WWE, with the exception of Jericho. The guy is the personification of a heel. As far as I'm concerned, Edge is the best Heel in the WWE since Ted DiBiase, and that includes The Game. Edge for my money, easily top 5 wrestler of the decade.
Christian Cage: For my money, easily the biggest mistake the WWE has made this decade. How in the hell did this guy not get pushed to the next level. In 2005 he was out popping guys like John Cena, gets a main event push, then gets shipped to the midcard of Smackdown, what? He plays the role of cocky annoying heel perfectly. He's a weasley character that you just love to hate. He is comparable to the Rock on the mic as far as direct relationship with the crowd. I am a Peep, and have been for a long time. Some question his in ring ability, sure, he's not the most technically sound wrestler, but he's solid in the ring, and he's not above lying on his back to put someone over.
Edge and Christian: You know, the more I think about it, the more I'm starting to believe they are the best tag team ever. In a time of people marking out for the Dudleys and the Hardyz, Edge and Christian made those teams look tame by comparison. Clearly at the time they were a step above their competition, which has translate today to their success as individuals. I can't recall another tag team that had so much success as a team, and then both went on to win multiple world titles and become the face of their Promotions. For my money, Edge and Christian are the greatest tag team ever.
