The problem for Berry is that he has only played four games (including the playoffs) over the last two seasons. Unlike Thomas, Berry's recent tape isn't inspiring. It might be a bitter pill to swallow for one of the game's best safeties from the first half of this decade, but he's absolutely in a "prove-it" phase of his career, because of the heel problems that have limited his availability and explosiveness. The Cowboys had Berry in for a visit first on Tuesday and seem most likely to spend starter money, betting on the 30-year-old's upside over in-house starter Jeff Heath. Berry is expected to go on more trips, yet may have to settle on an incentive-laden deal if he doesn't find what he's looking for.
