Chavo has the worst frog splash I've ever seen by a wrestler at that level; I don't know why he won't go back to the Tornado DDT... But I still put him over Kendrick. Whatever mythical potential Kendrick has is completely over my head. I certainly don't see him as the next Shawn Michaels; if anything, I see him more like the next Justin Credible... maybe. Would I take Justin Credible over Chavo? No, I would not.
I think that the biggest knock on Chavo is that he never really got out from under Eddy's shadow before Eddy died, and now he's never going to be seen as anything other than Eddy's nephew (as someone else mentioned earlier). This, however, does not equate to Chavo not being useful, and to me, Chavo is just big enough and his offense is just credible enough to be seen as a borderline threat to beat the upper midcard wrestlers. Kendrick, to me, is too light in the ass to be seen as a threat, and the one move in his arsenal that seems dangerous requires too much setup time to be taken seriously.
Frankly, I can't see either as a star. But, if I were starting a promotion from scratch, I'd hire a guy like Chavo before hiring a guy like Kendrick.
