Some fans demean Jones for his continuance in the sport 20+ years past his prime, and because he's only 14-8 in his last 22 bouts and has been knocked out six times. And yes, several of those knockouts were devastating.
....But what some fail to remember is RJ has never been beaten by an opponent who wasn't accomplished.
Should Jones Jr lose to Gunn, it would be a first of sorts because Bobby, who is also a bare-knuckle fighter, has never won a legitimate world title as a boxer nor was ever universally considered a legitimate top 10 contender in any division.
Fans can be harsh is their assessment of Jones but to his credit, he's not being beaten by run-of-the-mill opponents.
Roy Jones Jr: Losses
DQ (win) by Montell Griffin Rd 9
Montell entered with a record of 27-0; He'd represented the U.S in the Olympics and was 2-0 vs James Toney as a pro. In their first bout, Jones was disqualified after unleashing a combination on an already-hurt Griffin while the latter was on one knee. Five months later, Jones would knockout Griffin in less than a round in their rematch.
TKO 2 by Antonio Tarver, May 2004
UD 12 by Antonio Tarver, Oct 2005
A 1996 Olympic bronze medalist, Tarver had previously collected two light heavyweight titles before losing them to Jones in the first of their three meetings; He entered their first showdown as a bonafied world champion and with wins over Eric Harding and Montell Griffin.
KO 9 by Glen Johnson
Dubbed 'Road Warrior,' the tough-as-nails Johnson entered that bout as the IBF light heavyweight champion and had already collected wins over Eric Harding and Clinton Woods. Johnson would defeat Tarver in his next bout.
UD 12 by Joe Calzaghe, Nov 2008
Boasting a 45-0 record, Calzaghe was regarded as a top 10 pound-for-pound fighter and was the current long-reigning, consensus super middleweight champion. Nuff said!
TKO 1 by Danny Green, Dec 2009
Green, then 27-3, was a former WBC super-middleweight champion and former WBA light heavyweight champion, and was considered among the 2 or 3 best cruiserweights in the world at the time by some.
UD 12 by Bernard Hopkins, Apr 2010
Already an all-time great heading into this bout, Hopkins was a former long-reigning RING Magazine (lineal) middleweight champion and had boasted wins over the likes of Felix Trinidad, Antonio Tarver, William Joppy, Glen Johnson, Winky Wright and Oscar De La Hoya. Not long after this bout, Hopkins would become the RING Magazine (lineal) light heavyweight champion.
KO 12 by Denis Lebedev, May 2011
Ranked #4 at cruiserweight by The RING at the time, Denis was 21-1 with his only loss coming via a hotly controversial decision to then WBO cruiserweight champion Marco Huck. Sans 16 months in between, Lebedev would own a share of the cruiserweight championship from November 2011 to December 2016.
KO 4 by Enzo Maccarinelli, Dec 2015
The least accomplshed of Jones's conquerors, Enzo entered that bout as a former WBO cruiserweight champion and veteran of 41 wins with 33 coming inside the distance. He'd shared the ring with David Haye, Juergen Braehmer, Denis Lebedev and Ola Afolabi, and was certainly no stranger to high profile bouts and elite-level opposition.
The Roy Jones Jr record is a bit deceptive. We see 9 losses and assume he was embarassed by subpar opposition.
Should Jones defeat Bobby Gunn tonight and retire, let it be known 8 of his 9 losses occurred when he was well past his prime - and against accomplished opposition.
Jones dominated the boxing scene from 1993 to 2004 and was an exceptional multi-talented fighter with incredible speed, explosiveness and technical prowess.
The consensus Fighter of the 1990s, Roy Jones, Jr has won world titles at middleweight, super middleweight, light heavyweight and heavyweight, and is undoubtedly one of the greatest fighters ever.
