I can't help but think that you haven't really watched wrestling very long. Kane's debut was hyped for ages before he attacked The Undertaker, and Kozlov's title shot came at Suvivor Series, in a three way that was really a two way until Edge showed up. Anyway, that aside, I'm not really sure that you have a point.
The monster heel career trajectory is pretty much the same for everyone. Debut strong, move down the card, turn face, get released. Right now, we've seen Umaga and Khali follow this path, though Umaga got released for other reasons before turning face. Kozlov, debuted in 2008, is in the process of moving back down the card. Guys like Snitsky are a recent example ofbig guys too. Basically, once they've been stopped, they have fulfilled their purpose. One or two have managed to find extra dimensions and have stuck around, but for every Kane and Undertaker there are a hundred Big Daddy Vs.
There isn't one debuting right now, but there probably will be at some stage soon. I'm not sure that starting on ECW is tantamount to castrating them anyway, as long as they move them like they did Sheamus. After all, most of the others started off beating jobbers on the undercard.
