I like both of these kids...in a tag team. They are perfect as a tag team. Neither one has much of a personality (so it seems), and they have contrasting styles. Smith is the power guy, and Tyson is the speed/technical guy.
Smith seems to fit the WWE superstar mold a little bit more. Much bigger, and has the father's name to get him places. I'm not sure I buy into him as a WHC, but he's only 23 years old. His physique is nowhere near the stature of his father, but I'm not sure that's going to hurt him. He just needs to tone up a bit, and he should do well. Whether he is destined for World Championships, or mid card status, I don't know. But he should be around for a long time.
I like everything about Tyson Kidd, minus that stupid little patch of hair he has on the front of his head. I have a hard time taking him seriously with that hair do going on. But as far as wrestling goes, he's very good. But he's already 29, going on 30. Is that old? Not by any means. But what it means is that he has a much shorter window of opportunity to break into singles stardom than Smith does. I used to think his size hurt him, but I'm not so sure anymore. He's a high-flyer, but he is also a very technically sound guy. Little guys can make it big if they have technical skills, and do not only rely upon big spots.
I hope this tag team stays together for a long, long time. But I'm not sure they will, seeing WWE doesn't seem to give a shit about building good, long-lasting tag teams. They will probably break up sooner than they should, and both will be lost in the mid card (at least for a while).
