Jones likes to position himself as the expert on boxing; everyone else knows nothing. This is the same Jones who predicted Shane Cameron would prevail over an ageing David Tua in their famed 2009 encounter. Tua stopped Cameron in the second round.
Perhaps the most damaging criticism came from boxing literary giant Thomas Hauser. Muhammad Ali's biographer, prolific author and boxing authority, Hauser called the Parker-Ruiz bout "an embarrassment" and said neither was an elite fighter: "Joseph Parker has limited ability ... don't call this a world championship fight because that demeans the sport of boxing."
Unfortunately, 70-year-old Hauser demeans himself. His wonderful 1991 book, Muhammad Ali, His Life and Times, is recognised as the premier perusal of Ali. But let's face it, Ali was a god.
Once you have sat at the feet of gods, mere young contenders like Parker must look like false idols. Hauser seems locked in a time warp; to him, boxing was greater then, end of story.
Old age can also make you mean; it is hardly the fault of the fighters they are in an era of competing boxing organisations like the WBA, WBC, WBO and IBF, all bodies of rampant self-interest diluting the fight game with a quest for money and champions who are often not champions of the world in the correct use of the phrase.
Boxing's alphabet soup organisations are also not the only people interested in money. Ruiz and Parker aren't pretending to be Muhammad Ali and there is little point in shooting the athletes if you believe a sport has gone to the dogs. They can only fight what is in front of them; change isn't always good but comparing sporting eras is about as useful as an ashtray on a motorbike.
Regular readers of this column may recall, on October 22, a reminder that even if Parker won against Ruiz, he would be a world champ and not the world champ - a perspective less mean-spirited if said before the fight and not afterwards. Any objective ranking of the world's best heavyweights would have Parker at No5 (behind Anthony Joshua, Deontay Wilder, Wladimir Klitschko and Tyson Fury).
But Parker has plenty of time to mature and improve. Whether he can beat the giants ahead of him, seriously big men, is another matter. Sport is all about hope, even if boxing is often about bullshit - which affected even Ali.
Hauser forced Ali to admit the old tale about him throwing his Olympic gold medal in a river because of a racial incident was false. Someone had stolen it or Ali had lost it.
There it is - even the great old era, and the greatest boxer there has ever been, once had feet of Clay.
