if you think they were good choices, why dont you tell me why, cause id like to know
I didn't say that they were good choices, I simply stated that your "fact" is nothing but your "opinion".
Since you asked though, in my opinion;
Yokozuna was being pushed as a dominant force back in the day and was a logical choice to carry the Championship.
Rey Mysterio, as everyone so puts it, is very popular with a lot of people. The "face" champion is usually the guy that can sell the merchandise. The man can wrestle (unlike Mr. 2 move Hogan and Flair) and puts his all into his matches. Is he someone that should be a long term champion? Probably not. A lot of people like to pick on his size but if that's the case then guys like Shawn Michaels and Chris Jericho should have never been champion and if popularity was a reason not to be champion, then your championship list is going to be practically non-existent. Also Rey has a lot of pride in being the World Champion and that's the type of guy you want representing your company.
Jack Swagger is like Sheamus. It's new blood in the championship picture so that the WWE doesn't have to keep using the same tired guys over and over and over again.
You say it's too early for him then how do you explain Brock Lesnar or the Undertaker? Two men who beat very top guys early in their WWE careers to become Champion.
Undertaker, a year after his debut got his shot at Hulk Hogan and Lesnar beat the Rock a mere 5 months after his debut. By comparison, Jack Swagger debuted in Sept. 2008 and won his first World Championship in March 2010.
There are usually three factors that determine who will carry the Championship. Popularity, work ethic, and backstage politics. All you have to do is look at the list of Champions to know that's the truth. A lot of the time popularity and work ethic aren't even enough because of the crap going on backstage. Sometimes the occasional swerve would happen and you have some one like the Great Khali holding the Championship but it's usually those three factors that determine title picture.
