Jimmy,
I think his post comeback sucked and I watched it all. His offense was beyound horrible. His over acting was very grating. The build of the matches was ridiculous. He did have some stand outs, like the Jericho later series and the Undertaker WM matches. A lot of those other matches you praised I think are complete shit.
As for his early stuff? The Rockers was the highlight for me, outside of 96-97. I don't think his singles stuff was that good outside of a few good matches here and there. He was solid and everything, but nothing to build a case on.
So yeah, being a really good tag wrestler for 3 years and having two really good years in a singles while having 4 ok years and then a comeback of 10 years of shit is not a case to get someone on my list, let alone number one.
