Not a terrible mock at all.
But far from great.
In this scenario Dallas would use Jernigan as a 3T which he is explosive enough to play in a rotation.
Bailey is probably not better than Church or Wilcox but is likely a 3rd safety here.
Smith is a weakside LB option but he is really small for the position and may be a couple years away from having an NFL LB body.
Dozier is probably the swing OG day 1.
Sam is at best a rotational pass rusher but that's ok out of round 5.
Not a bad mock for helping add depth but no where near maximizing resources.
