Certainly not a 1st this year.
Besides, keeping a really good player like Gallup on the team for a full season at a low cost is worth draft capital by itself, not to mention the 3rd-4th round comp pick he'll produce.
A fully healthy OL, Dak/Zeke/Pollard plus a receiving corps of Cooper, Lamb, Gallup, Pitts with Schultz, Wilson, and Jarwin as backups is one of the strongest offensive lineups I've ever seen. That's greatest show on turf level good, maybe better from a pure receiving talent perspective.
Having a lineup that strong is something you'll always remember (if Pitts is as good as he looks, and players stay healthy). A good coach will turn that into an unstoppable unit. If they don't, you've seriously got to question their skills.
The defense will improve in any case (it can't get worse), especially since most of the draft and FA would have been dedicated to it.
