"I got a couple of freestyles," O'Neal said. "It's all competition for me, so when I hear other people that say, 'I'm a better athlete-rapper than Shaq,' I gotta step up."
"Nothing personal. I just have to let these people know who paved the way."
Some of the athletes makin' waves in the rap game include Lillard, who's been considered by fans to be one of the best, lyrically, in any sport.
There's also Brown, who's made catchy tracks like "Put That Sh** On" ... as well as former NBA star Iman Shumpert.
