Shakur Stevenson has only watched ONE ROUND of tape on the man he's fighting Tuesday night ... telling TMZ Sports it's obvious his opponent just ain't in the same class.
22-year-old Stevenson -- dubbed the next Floyd Mayweather -- is taking on Felix Caraballo at the MGM Grand in Vegas ... the first major boxing match since the COVID-19 pandemic began.
Stevenson is undefeated (13-0) and the reigning WBO featherweight champ. Carabello is on a 5 fight win streak.
But Shakur says this will be easy work -- and he's asking fans to tune in because he promises to put on a show!
