40+ I'll say---------

1) Hop-- Still lookin sharp in all phases.

2) Moore-- The Ol' Mongoose beat Durelle in a LHW title defense, a draw with Willie Pastrano, & put Marciano down.

3) Foreman-- Was being outboxed by Moorer but the end result is what counts. HW champ @ 45 yrs of age.

I wouldn't try to argue flip flopping these 3 guys in any position to be quite honest. Especially Hop & Moore.
