Surely there has never been someone as old as Sting in as many high quality matches in a year
I'm not that versed in Lucha to see if there's someone. It would be cool if Casas sees this as a challenge and goes for it, he's 1 tear younger than Sting.
God didn't have many matches, though he does have two notable ones (the tag match at One Night Stand 2006 and really fun Lawler match).
The last time Flair saw in ring action was in 2011 when he was exactly Sting's age right now. Never saw TNA during those days, I just know he was hilarious on a wheelchair
Fujiwara had a lot of matches when he was 62 but I have no clue how they were, don't remember watching any. And Tenry only had 1 match at that age so he would be out.
