Dak, Cooper, Gallup, Lamb, Martin, Biadiasz, Conner, Collins, Tyron, Jarwin, Mcgovern, zeke, pollard -- offense
Dlaw, Gregory, Hill, Gallimore, Diggs, Brown, LVE, Thomas, and some young guys -- defense
The defense does need talent and toughening, but you have 2 really good DE's in Dlaw and Gregory, a young corner that might be pretty good, LVE is good when he is healthy, and some young guys who can step up.
If they are able to get 2 or 3 defensive players in the draft that can play, a cheap free agent or 2, it will make a big difference. If the offense is healthy and scoring points, playing with a lead, and controlling the clock, it will make the defense even better.
I don't get people saying the Cowboys need a rebuild. They have a ton of talent.
