You see a pattern in the examples you listed? All great workers who carried Nash to great matches.
I forgot about the Undertaker WM12 match. Taker was not a great worker at that time. That was Taker's best mania match up to that point and possibly his best match period at that point other than maybe with Yoko (who was also a good worker) and Bret
Also, the HHH matches in the past 10 years were very good as well, not "classics" but better than anything Kane was in during that time really
