Re: What if Kane didn't work out?
Brian Lee was in DOA at the time, as Chainz. Like you say though, he was a little on the short side to pull off the character. One of the major things that made Kane so impressive was that he stood taller than Undertaker.
At the time of Kane's debut Brian Lee was still in ECW, wasn't until later in the year he returned to WWF. I'm sure I read somewhere years ago that Kane's boots were boosted to make him appear taller when he first appeared, but I guess even if that was the case Brian Lee would have had have worn platforms.
