As much as they hyped the whole "fan vote" thing, I still don't think it had as much weight as was implied. Clearly they were high enough on him to not only let him be on the show, but to win it as well. He's been in two matches and lost to established guys. As much as I fucking loathe McIntyre (make him disappear, please), he's been active for a while and held the IC title for a few months. It makes even more sense now to not have him lose to a "rookie" if they were preparing him for the tag titles. Chavo, despite WWE's misuse of him, has held nearly a dozen championships and is a great worker, in addition to being a seasoned veteran. They probably just want Kaval to get some work in and are emphasizing that he's a "rookie", who still needs to figure out his game in order to compete with the big dogs. We obviously know that isn't the case, but I'm guessing that's how they're treating it. They could give him the underdog treatment in making him lose a bunch of matches before finally pulling off a big upset, which could actually do even more to get him over, in the grand scheme of things.
In the two matches he's had, he's put on a decent show, so they're at least letting him show off a sample of what he's capable of. I think he'll get a decent push at some point, probably sooner rather than later, and will end up with a mid-card title. I don't see him being a world champion, as he hasn't got the size that WWE tends to look for, and at this point, while I am a fan of his abilities, he also hasn't really shown me that he's at that level. Be patient. I think they know what they're doing with him, but it's going to take more than two matches to figure that out. If anything, he's lucky he didn't break his neck the way McIntyre dumped him on his head, so we should all be grateful for that.
