Didn't really get Trips/Eddie either other than that one match on the Raw draft show in 04. Did Cena/Eddie ever happen? I would have loved to have seen one more Trips/Shawn match (don't shoot me lol) at this later stage of their careers. HBK/Mysterio happened that one time on SD in 2009 I think.
Cena and Eddie had a feud back in 03. PARKING LOT BRAWL.
EDIT: HBK/Rey happened twice, Eddie memorial show then SD in Jan 2010.
They really set the bench mark and I honestly don't think that can be beat. I mean you're going to have to be pretty creative and pretty daring to even think about beating it. I mean a 300 pound man going falling off a 20 foot ladder in the middle of the ring through four tables on the outside, I don't think any other 300 pound man could pull that off, sounded like a legit car crash.
It's why TLC II had the inevitable recycled spots come WrestleMania 17. Only a few, but fact remains. Original set the bar SO high. Then they add in Chris Jericho & Chris Benoit a few weeks after and TLC III ends up being near the level of TLC I. So they managed to change things up to keep it great. I'm a mark for nearly every TLC match so I'll continue to show my love for the gimmick.
(I say this as last night I watched a TLC match that I legit didn't like. ha.)
