With the History of McCarthy speaking loudly and the needs in Dallas theres no doubt in my head, one of these guys will be the pick at 17.
Ill take it a step further and say if both are still there at 17 the pick is Delpit.
They used the word ballhawk at S. McKinney is better suited to playing closer to the box. As he's not a natural fit for a single high. He looks like a taller version of Woods. I wouldnt say he's a better box safety then woods is now because Woods puts it down, his faults come in coverage. As does McKinneys.
Delpit was bad at tackling in 2018, he improved this past yr. He could improve more but the point is he improved from 18 to 19. Saying this, he is an ideal fit for this team and what the coaches have talked about putting emphasis in the S being a ballhawk, which Delpit is. So IMO if he's there at 17, there no doubt in my mind that he's the pick.
Either one would improve this defense, but if McKInney is the pick i think they bring in a guy like Clinton Dix to play FS and playing McKinney at SS.
