Cintrón found
wrestling and boxing to be an outlet from his personal troubles, so he started spending more and more of his time practicing those sports. While attending
William Tennent High School in
Warminster, Pennsylvania, he became an accomplished high-school wrestler on the same team as actor
Mike Vogel. After competing at William Tennent, Cintron wrestled at Thaddeus Stevens College of Technology a Junior College in Lancaster, Pennsylvania.
In April 2007,
Floyd Mayweather, Jr. publicly claimed that any boxer could make the transition into
mixed martial arts and win. In response,
Ultimate Fighting Championship's president,
Dana White, issued him a challenge to fight the promotion's lightweight champion,
Sean Sherk. Mayweather later said that he did not wish to compete in the discipline. However, Cintrón stated that he was willing to fight Sherk in his place.
[3] "I want the fight," said Cintrón, who was 27-1 with 25 KOs. "I can wrestle. I can box. I can beat those UFC fighters at their own game. Tell Mr. White to make me an offer and I'll take on his guy...."

Seven years later, Mike Sloan of
Sherdog argued that "If Cintron [sic] would have had the opportunity to compete in MMA when he first got into boxing, he would have torn most of the lower weight divisions asunder" and "would have been a top contender in MMA."
[4]Sloan argued that his wrestling background and "ferocious banging style" represented "a dynamic combination that would have given MMA contenders all sorts of trouble" had he completed the transition in his prime.
