And drafting is not an exact science. The fact the Cowboys put all their eggs in the draft basket is idiotic but some fans just lap it up when Jerry and Stephen talk about it. Just look at last year, other than bringing Hankins back, the Cowboys ignored DT in free agency assuming they'd fix it in the draft. They took Mazi Smith who was a non-factor last year and surprise, surprise, we had DT issues much of the year.
A great draft is hitting on 3 guys. The Cowboys, given their total disgust of FA, need to hit on 4-5 guys in the draft. That's unlikely. And hence why they always seem to have issues roster wise.
How much easier would life be if you said, hey, let's go out and sign a legit TB and maybe a quality interior OL? Because then, you've given yourself flexibility in the draft. The Cowboys do no such thing. Since the Carr signing, they have put all their eggs in drafting to fill their holes and what has that resulted in? Nothing.
