He was a 4th rd. pick by the New Orleans Saints in the 2009 draft. A little tid-bit of info: "Vaughn is a physically imposing defender who has a lot of upside. He has great size, speed and athleticism. He positions himself well and delivers jarring hits. He’s always around the ball and looks to create turnovers. He’s aggressive at the line of scrimmage against the run, but even though he’s quick, he struggles in coverage. He has to locate the ball quicker and improve his ball skills." - Chris Steuber, Scout.com
