You could have saved yourself from writing "prime" 332 times by putting "(all in their prime)" at the start.
I would say just honestly, the Roy Jones Jr at heavyweight vs the John Ruiz fight. He was the perfect specimen, 191 pounds or 199 (if I remember correctly) pound for pound #1. Albeit he would have to face Lennox Lewis to further prove this. A cruiserweight vs a super heavyweight to see who is the best heavyweight head to head.
Here I go: the guard of a winky Wright, The conditioning of a Juan diaz, The heart of Deontay Wilder, The recuperative powers of Tyson fury, The head movement of an old school Mike Tyson. The build of a Lennox Lewis. The right hand of Deontay Wilder combined with the power of a tommy Hearns, The left hook of Tua or Frazier. The sheer strength of a George Foreman, Hand speed of Roy Jones junior, Chin of ray Mercer, The indomitable will of a Miguel Cotto, The left or right to the guts like Mickey ward, The uppercut of a Tyson. The switching stance of Terrence Crawford, The hard thudding body work of an Errol Spence, The left hand of a Pacquiao With the elusiveness of a Chris Byrd!
