Ice Cube was recently on ESPN's SportsCenter promoting the new N.W.A biopic Straight Outta Compton and he did a segment for them called "Ice Cube Judges Athlete Rappers."

In the segment, Cube listens (through headphones) to tracks from Iman Shumpert, Serena Williams, Clint Dempsy and John Cena, to name a few, and comments on their sound and flow, etc.

So, who does Ice think can rap? Well, check out the video above and see what famous rapper he compares John Cena to, which athlete Ice says "has bounce with his flow" and which athlete's track just makes him shake his head and say "no."
