I was at a wrestling site, there was an article on the Undertaker's top matches of all-time. Looking at the list, you'll see he had some matches with the great ones. But not just one match, he had a series with most of them. The Phenom has had a pretty extraordinary career.
- Kurt Angle(They had some nice matches at SD TV shows, and SD PPVs).
- Bret Hart(They had some solid matches in 1996, and 1997 with great workrate).
- Shawn Michaels(In late 1997, they put on a trendemous HIAC, plus a good Casket match at RR98).
- Brock Lesnar(Amazing HIAC match in a 2003, and good feud all-around).
However, I don't think none of them could compare to the infamous matches with Mankind. Just, amazing stuff.
They had the HIAC, they had a Buried Alive, they had a Boiler Room brawl, plus the usual normal singles matches. These guys knew how to co-exist in the ring, and it really showed. If you've seen the HIAC match, you'll never forget it. And not just for the two main spots, either. The Boiler Room brawl from the Summerslam PPV, was epic too. It was pretty revolutionary for it's time.
I honestly believe that Undertaker vs Mankind is the greatest rivalry in the history of the WWF/E. As a whole, I think it outperforms everyother rivarly including the historic Austin vs Rock.
