It would make VERY little sense for Christian to return into the World Title picture, if he can't keep the I.C Title how would he make it to the World Title?
It's interesting to note the range of descriptions inspired by Christian on wrestling boards. In the past few years, we've read posts by people on this forum who think he's absolutely the greatest thing to ever come along; they seemingly can't figure why he hasn't been given a lengthy reign as world champion. These folks have told us that he was the driving force behind the Edge-Christian team.....that he was so much better than Edge as a performer it was silly to even compare the two.
Personally, I find him to be a useful mid-carder. He's terrific at working a match, but so are many other people. He can talk a pretty good game, but many others are more dynamic on the mic. He's got a pretty good presence about him and is capable of giving some good promos.
When he returned from TNA several years ago, it appeared that Vince McMahon wanted Christian to pay some dues before boosting him to the position in the company he previously held......and, sure enough, after a long period of playing second fiddle on ECW and Smackdown, he restored his good name and was surprisingly inserted as champion, finally losing to Randy Orton. Christian seemed a good match for Orton; he wasn't in Randy's league (as a presence), yet he acquitted himself well. After two short runs as champ, Christian returned to the mid-card until his ankle injury took him out for a surprisingly long time.
If the injury hadn't occurred, I don't know that anything would have developed differently, and I don't think any plans for him were altered because of his lengthy time away.
I think Christian is now right where he belongs: a middle-of-the-card guy with enough charisma to occasionally challenge for one of the minor title belts......with an occasional foray to the top of the roster when the champion needs someone to give a credible, though temporary, challenge.
Okay, so Christian just lost the IC title? Don't worry, he'll win it again somewhere down the line. Things are proceeding in the manner they should.
