Roy Jones Jr. fought for the World Heavyweight Championship against John Ruiz and weighed 193lbs. Watching the fight Deontay Wilder Vs. Roy Jones Jr. from the perspective of that fight I came to the conclusion that Roy Jones Jr. won by unanimous decision. Why? It all boils down to whether Wilder would be able to accurately land just one "bomb" (like Antonio Tarver) or not. And I don't think Wilder would have succeeded, but Roy Jones Jr. was an elusive target for all 12 rounds. Precision is not Wilder's strong point, and I wrote off the option that Wilder would win this fight on points. P.S.I apologize for my bad English (google translate)
Look, I'm a big fan of RJJ. My username is a homage to RJJ. Wilder can afford to make plenty of mistakes. RJJ can't make one mistake and that's hard to do in 36m of combat. RJJ did get stunned at one point by Ruiz. Imagine if that was Wilder.
The Deontay Wilder that fought Luis Ortiz had a pretty decent jab going, Roy with his super middleweight frame doesn't get past it.
Roy isn't dumb enough to even consider getting in the ring with Wilder. Roy took on Ruiz because he knew Ruiz was awful
Roy knew he could beat Ruiz because it was a good style match up for him. He wouldn't have beaten any fast top 10 heavyweight with KO power imo.
