Josh Taylor made a big statement in May, when he defeated Jose Ramirez to win all four major junior welterweight belts. Taylor had another opportunity to show the world that his victory wasn't just a one-off this past weekend, when he faced mandatory challenger Jack Catterall. But while Taylor won a split decision, many boxing experts thought Catterall deserved the nod. Even the British Boxing Board of Control announced days after the bout it would investigate the scoring.
Some of our panelists also believed Taylor lost the fight, prompting them to drop him down the rankings. Some took Taylor completely out of their lists.
ESPN senior boxing writer Mike Coppinger dropped Taylor from his P4P rankings altogether, saying it's hard to keep him even after the victory.
"Taylor is undoubtedly a pound-for-pound talent, but it's tough to justify a top-10 ranking after such a lackluster performance against an untested challenger," Coppinger said. "Catterall might prove to be an elite boxer with time, and the decision wasn't the robbery some suggest. Perhaps Taylor was weight-drained and will return to form fighting one division above at 147 pounds. He'll have ample opportunity to reestablish himself as one of the best pound-for-pound boxers in the world at welterweight."
ESPN writer Michael Rothstein agrees, noting he thought Taylor lost the fight.
"Taylor may still be an undisputed champion, but after seeing him fight against Catterall, his pound-for-pound ranking took a major hit," Rothstein said. "Now that he's talking about going up a weight class too, he needs to show some dominance at 147 before I would consider ranking him again.
"Taylor is a good fighter, but there are many good fighters in boxing."
Did that mediocre performance cost Taylor his spot in the top 10?
