I guess it depends on what you mean by "need"...
Positions where we have a weak starter (1st-3rd round targets):
DT: Wyatt is at a make or break season. He has flashes, but isn't a complete starter. Losing Slaton hurts depth plus there is a realistic thought that it will be Clark's last year puts depth here at a real need. This is where I would bet our 1st round pick goes due to the depth of the position in the draft.
DE: We are really leaning on improvements by LVN, Cox, and Enagbare to take pressure off of Gary. This might be our weakest starting position on the team. Really banking on development by LNV and Cox and a year removed from injury for Enagbare. At a minimum, you have to add another body here for depth/competition.
This is where I'd have loved to see a vet FA addition instead of another draft pick. Then the other 3 positions here fill our first 3 draft picks.
WR: We have a lot of good raw talent, but no one is taking the next step. I think you need to keep adding talent here especially with Watson's injury. Our offensive numbers say we were fine, but it certainly feels like we could greatly improve here.
CB: I'm assuming Alexander is gone. Last year, Nixon, Valentine, Bullard, Ballentine, and Stokes were very solid (which might be more a testament to the Defensive scheme and coaching than the players). Hobbes is an upgrade over Ballentine or Stokes. It wouldn't surprise me to see a 1st/2nd round CB, but it also wouldn't surprise me to see one picked later instead for depth only. It would surprise me to see none picked. I think the coaching staff likes the strength of the CB unit more than the fans do.
Positions where we could use depth (4th round and beyond):
OL: We have 6 starting quality players (maybe 7 depending on Monk). So I don't see a strong "need" here for starters. But we certainly need depth. I doubt we see someone picked early for OL this year, but our favorite 4th rounder T/G is out there somewhere.
TE: Kraft had a bust-out year. Musgrave has tons of untapped potential. But really not much beyond that. TE is a draft and develop position, so grabbing a mid-round development TE should be a goal. You have Sims or Swinson available for the dedicated blocking TE role. And not that I want it... but we seem to like the HB types. That might be our TE adder as we don't have that person now.
LB: Walker, Cooper, and McDuffie are pretty well locked in as the starters (like it or not) and Hopper is still developing at depth. But we literally have no other off ball LBs on the roster. As a position for ST and for depth, there will be 4+ people added here before TC. At least one draft pick, a few UDFAs, and probably a vet added.
Positions where we "seem" fine
QB: Not a need with Malik and Sean on the roster, but we've started to create a habit the last couple of years. With fewer late picks this year, I hope we bypass this habit for a year. Maybe sign Rodgers as a backup.
S: Any newcomer might be hard pressed to find a spot. McKinney and Williams were wonderful (maybe the best since Butler and Sharper)? Bullard was good at nickel, but has obvious upside still at safety. Both Anderson and Oladapo looked good in limited views also. Five deep at safety, with quality starters and upside development players. Ideal position.
RB: For a position that keeps 3-4 players, having Jacobs, Wilson, Lloyd, and Brooks is pretty deep. A few UDFAs should be the only priority. Again we have quality starter, good depth, and upside potential.
ST: I keep hoping we find a LS replacement, but not enough to draft one. K and P are strong enough to not bother drafting also. Nice to be back in a position of comfort at K.
