So far in free agency the Cowboys have proven to be good closers. The Cowboys have signed seven of their eight free-agent visitors. The only player not to sign was tight end Kellen Davis, who returned to Chicago on a two-year deal.
Bush, 27, is considered a top special teamer and led Green Bay with 12 tackles. Defensively the Packers’ coaches credited him with 21 tackles, 1.5 sacks, two interceptions and eight pass breakups. He started two games for the Packers in 2011.
