Is it a bird? Is it a plane? No it's Supermod!
Honestly, it'd probably be hard to make a story out of Taker vs Sting only because the two (when sting's gimmick first started) gimmicks are similar. Fact of the matter is, it'll be for nostalgic purposes. Hell I even had a tough time trying to think up stories in TEW for the two.
Undertaker: I've beaten all comers
Sting: Not ALL
There that took me a second to think of.
