No, it's not clear. Despite his size, Bernadeau is probably better in a Zone scheme. The only players on roster that are questionable in the Zone scheme are Cook and Livings. Even Livings played in space a lot in Cincinnati, but he appeared to be a little slower in 2012 than he was while with the Bengals. Cook might not even make the team, leaving Livings as the only player that is not a perfect fit in the ZBS. I don't see any players on the roster that are dominant power-man-blockers. Livings is the closest, but none of the others are bulldozers.
