So far, I've narrowed it down to three.
Lee Haney - 1991 (Haney finally learned how to peak

)
Ronnie Coleman - 1999 (it's the closest Olympia version to the 2001 ASC)
And, in a bit of a shocker to some,
Brandon Curry - 2019 (Mr. O from the waist up for years; went to Kuwait, fixed them legs, and got an ever BIGGER back).
