The Dallas Cowboys continue to churn their roster this off-season with the release of undrafted rookie tight end Paul Freedman of Virginia and the signing of veteran tight end Dante Rosario. Rosario was originally drafted in the fifth round (155th overall) in 2007 by Carolina out of Oregon. He caught 99 passes for 1,106 yards and eight touchdowns in 27 starts over 91 career games. Rosario played four seasons with the Panthers before signing with Denver in 2011 as a free agent, but was released on final cuts. He signed with Miami and played two games before being released and re-signed by the Broncos, where he finished the season. He signed with San Diego last year and played in 13 games with two starts. The Cowboys have six tight ends on their roster. They are Colin Cochart, rookie Gavin Escobar, James Hanna, Andre Smith, Rosario and Pro Bowler Jason Witten.
