I had so much hope when he came in, but now he's turned into a giant waste of space. Every match he's been in lately, he's botched something. (Dudleys vs. Evolution, etc.)
It doesn't help that they book him against faster guys like HBK and so forth, but it also doesn't help that there are a couple of other guys as big as him in WWE now. Seriously, remember when the Undertaker was one of the ONLY big guys? How many now? Taker, Kane, Batista, Heidencrapper, Matt Morgan, Lesnar, Big Show, Goldberg, A-Train, and who knows how many more in their sights. Big guys aren't as exciting because there's so many.
