WWE originally wanted to do a Rey Mysterio & Oscar De La Hoya vs. Floyd Mayweather & MVP match at WrestleMania, but that fell through after De La Hoya said that he was not interested. After the De La Hoya part fell through, Vince McMahon decided he wanted to put Big Show in this angle and push him hard upon his return. As late as this weekend, there was also talk of doing Rey & Mayweather vs. Big Show & MVP match, but then talk switched to using Shane McMahon in MVP’s place. It’s all moot point now due to Rey’s injury, so it will be Big Show vs. Mayweather in some sort of match. Also note, it won’t be a “shoot” match.
Shane McMahon had been pushing hard for WWE to use Floyd Mayweather ever since meeting him several months ago in Las Vegas. Shane is a big MMA fan who enjoys hanging around tough guys. Every year he pushes WWE to do some sort of boxing/MMA/K-1 style match.
