Free safety wasn't a need? Really? They had to shift their #8 pick from his natural position. The only reason Whitner was playing FS last year was because the Bills had no viable candidates to replace Simpson. They realized that Whitner was the only one who could play FS reasonably well, and that Scott could man SS without being too terrible. They drafted Byrd because he displays the skills that make very good free safeties, and they want to move Donte back to SS.
