The greatest feuds to never reach Hell in a Cell?

[Mr. Nerfect]

This is just something I ponder occasionally. Which feuds were deserving of the Cell, but never went in there. I suppose you can go back in time for these, too, and list matches that never made it in there because the Cell had not been invented, or because they were in another promotion.

Personally, the two biggest ones for me would have to be Stone Cold Steve Austin vs. The Rock, and Stone Cold Steve Austin vs. Triple H. Austin vs. Rock was just iconic. Putting the two in the Cell with the WWF Championship on the line would have gotten some buys. Triple H and Austin's feud was really hot for a while in 2001. They had the 3 Stages of Hell, but it never really went to the final battle inside Hell in a Cell.

Oh, and of course there was Austin vs. McMahon. Austin slapping around Vince inside the Cell would have led to some mark-out moments. Vince and Shane have never really been afraid to bump, but I could have just seen Vince escape form the Cell, and climb to the top, as Austin pursued, and Shane ran down to help his father. Austin throws Shane off the Cell through one table, and then he sends Vince through the other (with Vince probably dangling off the Cell to just make it as small a fall as possible.

The Undertaker vs. Kane, given the type of characters they are, seem like they were made to take their grudge since childhood into the Hell in a Cell concept. Technically, they were on opposing teams during one match, but I'm talking one-on-one.
