Personally, my feeling on TBK (look how close his acroynm is to HBK...omen?

) is that I'm not feeling the it factor from him right now. The important part of that sentence, however, is right now. I see Kendrick as an Intercontinental, US, or ECW Champion any day of the week right now, and when he was drafted there was no way I could have ever expected that out of him. Honestly, I think the best thing for this guy would be to go to ECW and have a good feud with Matt Hardy. As far as the potential of main eventing a pay per view...well, it's not something I'm seeing for him right now. Obviously he is small, although he can change that. He's on the short side but if he packed on 20 pounds (hopefully of muscle) the general image could change. Besides, he outweighs Mysterio by 20 pounds already and is two inches taller. He's got a great spot on the Smackdown midcard, and it's not like he needs to jump up to the main event right away. There's nothing wrong with him being where he is, and in several years he might get there.
That said, here's some eternal midcarders as I see 'em,
Carlito - I just don't see him making the main event in the WWE. Give this guy any midcard title you want, he's great for it. But Carlito as a world champ...man, it's just not there. It's time like these I realize how huge the gap between the midcard titles and the world titles really is. There was a time when we could have said, "Well, he's been Intercontinental Champion, so he should be gearing up for the main event soon." Nowadays the feeling is more like, "He'd be a great IC Champ, but no way will he ever get the world title." There's guys who have Hall of Fame careers who's great WWE accomplishment is the IC Title. Anyway, Carlito. His tag run is exciting and he's shown he can do face or heel and work out well, but his mic skills really aren't that great. He's a pretty good wrestler and I don't see any problem with him maybe main eventing ECW one day. But I can't see him ever hitting the main event. I'd say the same for his brother, but because he's so new, I can't penalize him this early.
Mr. Kennedy - I love this guy, and it hurts to say this, but I don't see him ever getting out of the midcard because he's just too injury prone. Every time he gets on a roll he gets hurt, and leaving to do a movie didn't do him any favors either. Kennedy is one of the best talkers on Smackdown, and can get a crowd majorly pumped with his whole entrance business. But just looking at his history...he got the MITB case which he lost to injury, and he very well could have become world champ off that case had he managed to last till WM. Then again maybe he was always supposed to lose to Edge, we can't know. But certainly getting hurt there didn't help him. Then he got himself suspended, which is another momentum killer, went up to Wrestlemania with nothing special and made a token appearance at best in the MITB match, when he could very well have become world champ that night. Then he leaves for a movie, returns for a whopping two months, and gets hurt. The only saving grace Kennedy has is that the fans love him, and if he can stay injury free maybe one day he'll become world champ. I'd love nothing more, I think he's awesome. But one more injury and long term abscence might condemn him forever to the midcard.
