my first day of draft dreams....
Shepperd is a very good corner but we have to remember that he played for a blitz happy defense. This means that he could, and did, play man coverage very well but it also means that he didn't have to cover for long. I would imagine that a lot of his interceptions were because of a QB throwing bad balls under duress. I would guess that he would not be as effective while trying to cover his man for five seconds as McKenzie does.
