No but based on data certain positions can be found outside of the 1st round vs in it.
QB and CB are two positions that data shows you have a significantly better chance at getting an impact player in the first round vs anywhere else in the draft.
RB and LB show the value outside of the 1st round is much better.
Utilizing data which the Cowboys do not do shows there's certain position that carry better value and where you should draft certain position unless they are a once in a generation type player.
1 tech you do not draft in the 1st round unless he is Vince Wilfolk.
MLB in the top 20 unless he is Luke Keuchly
TE... like ever
RB is another position you should never draft in the 1st
You could even argue interior shouldn't be drafted top 20 unless a unicorn is there.
