From all accounts, Melton's visit went well. According to sources, the medical checkup on his surgically-repaired knee came back fine, and he was able to re-connect with the coach that developed him into a Pro Bowler with the Chicago Bears, defensive coordinator Rod Marinelli.
The Cowboys will continue meeting with free-agent defensive end Jared Allen, who arrived in Dallas Monday night and met with coach Jason Garrett and several assistants.
The Cowboys are looking for defensive line help, but so far in free agency have maintained a disciplined approach despite the release of DeMarcus Ware and the loss of Jason Hatcher. Ware has since signed with the Denver Broncos and Hatcher signed with the Washington Redskins.
The Cowboys have roughly $7.6 million in salary cap space. Depending on the structure and lengths of deals, they may need to come up with more cap room by either restructuring or releasing players.
