Re: A Stone Cold vs. Ken Shamrock 1998 face vs face feud
True. But in the Attitude Era promos were very important. They were very promo heavy in this era. So, the top guy of the company feuding with a guy who for all intents and purposes would be a mute (or, like you said, short and sweet promos) would have been very difficult to book around, especially as the top feud of the company. You can get away with that sort of thing with a mid-card feud, but not when you're feuding with the top guy in the business in a very promo heavy time period.
And I'm not convinced the matches would have been all that great. Shamrock was obviously a UFC fighter. But he never became a great WWF worker and was still very much finding his way in '98.
