Mr. Irrelevant, Ramzee Robinson, is the NFL's Best Rapper
According to Winning the Turnover Battle (and thanks to them for the info), Robinson went by the name of "Hood Doc" is his P$C days. Like them, I've never heard him rap, despite owning a P$C album (25 to Life, don't rush out and buy it). Robinson apparently gave up the rapping when he went to Alabama to play football.
I wish him the best of luck in the NFL, though the Mister Irrelevant spot does not have a great history of producing regular NFL players. He was lucky enough to go to Detroit, though ... if the football doesn't work out, 8 Mile is right around the corner.
