Edited to fix the name drop, and I completely agree. I really like this guy. I got him in the mid second in the forum mock, and he was my backup FS, due to having Jairus Byrd back there. I liked being able to let him sit for a year and learn behind a vet whose coverage skills were supreme in his day.
Yet after some more thought on the subject and discussions with @-Truth- after the pick, I think I agree with him that Karl Joseph's best fit is as an all-around SS. His game translates best to playing out of the box though. He's solid in coverage and tackles with ferocity in space. He never takes a play off, and he's one hell of a competitor.
