From my time, one guy comes to mind when I think about being able to bring back a player in their prime to make an impact right now for this team, and that player is DeMarcus Ware.
Ware finished his Cowboys career at No. 1 overall in sacks (117) and No. 1 overall in forced fumbles (32). Ware had ten or more sacks in at least seven straight seasons, making him the third player in NFL history. (Reggie White and John Randle).
He led the league in sacks twice, earned seven total All-Pro nods (four first-team and three second-team), Nine Pro Bowl selections, and selection to the All-Decade Team for the 2000s. Expect an invite to the Pro Football Hall of Fame and the Cowboys' Ring of Honor to follow soon for Ware.
I know other people will pick some other guys, but I would love to line him up with Dan Quinn and Micah Parsons and see what they could do together. Ware is one of my all-time favorite players, and I also have grown to love watching defense. I know the league is all about offense, but it is so enjoyable when the defense can go out and hit the offense in the mouth and make it tough on them to get anything going.
Guys like Dez Bryant, Terrell Owens, Terence Newman, and others are a few others I would love to have back. I would include all the greats from the 70s, 80s, and 90s, but only being able to watch highlights isn't the same.
Who would you love to see suit up again in a Cowboys uniform?
