There's really no such thing as a "shut-down" corner nowadays. There's some really great man corners like Revis and Asomugha, but even Champ Bailey can't be a "shut-down" corner with the rule changes the past 4 years. I can't really think of many CB's who can lock down on a No.1 WR like Fitzgerald or Johnson and completely take them out of the equation. Finnegan certainly can't take those guys out of a game, so to me he isn't a shut-down CB. He's maybe a top 10 CB though.
