Seabs I think you're the only other person I've seen say they didn't know what HBK's role was in Taker/HHH. I did enjoy the match, but I had no idea what Shawn was supposed to be doing for the majority of it.
It was just the way he was taking one side, then the other, then screwing the first guy (no homo). It all got a tad too confusing for my liking. I can't really remember much about the match though apart from Shawn, the superkick/pedigree combo and the chair shots, which isn't really a good thing.
