And on Smackdown too, wasn't it?
Yeah, this was mind boggling, I mean Taker has always had a history of being willing to put new guys over (Yokozuna in 1993, Mankind in 1996, Angle in 2000, Lesnar in 2002, hell, even Khali in 2006 - which was comparable to Brock squashing Cena at Summerslam this year) on big stages, but this was a random throwaway episode of Smackdown. What's more weird is how the finish came across. Kozlov countered the Old School into a Powerslam and pinned Taker. It came across like Taker simply fucked up, rather than Kozlov actually defeating him. An upset nonetheless, as nobody expected Kozlov to go over.
It was a kind of strange path to the Shawn Michaels/Undertaker Mania match. Kozlov beats Undertaker, then a short time later, Michaels beats Kozlov, so there is a bit of buzz going in of "Michaels defeated the guy that Undertaker couldn't beat." Then a few weeks later, Undertaker beat Kozlov so the whole thing was meaningless.
