We told you about Slick Rick getting booed at halftime of the Knicks-Nets game, and about Frank Isola of the New York Daily News getting all kinds of grief on Twitter for wondering whether Slick Rick was indeed a hip-hop legend. Slick's got nothing to prove to anyone anymore, but after hearing this mess of a medley he put together at the Barclays Center, it's easy to see why someone unfamiliar with his work might question his credentials. Yeesh.
