To think about where a FA fits, I figured a review of the depth chart makes sense:
QB (2): Love, Ridder, McCord, Drones - Seems like we don't have much of a backup this year.
RB (3): Jacobs, Lloyd, Brooks, Strong, Martinez, Nixon - Lloyd brings upside and injures... Not much depth there, but I'm guessing there are good candidates at cut-down if needed.
WR (6): Watson, Reed, Golden, Williams, Melton, Moore, Keeney-James, Nayor, Sheppard, Sturdivant - Three strong contributors. Williams could be interesting this year. I think they have some good development candidates too in JKJ and Sturdivant. Moore is probably KR/PR only.
TE (3): Kraft, Musgrave, Whyle, Dabney, Swinson, Falayi , Maryland - Dabney might have a bit of upside as a blocking/recieving TE, but we could use more two-way TEs, especially with Kraft coming off his injury.
OL (10): Tom, Morgan, Belton, Banks, Rhyan, Kinnard, Glover, Williams, Burton, Jennings, Monk, Barnhart, Barrett, Gesky, Banks, Cooper - Kennard as our main T backup with an inexperienced Morgan and injured Tom at the Ts with Glover as the "development" candidate doesn't feel great, but I don't think it will improve. Zero experienced guard depth either, but I like William's upside.
DL(6): Wyatt, Hargrave, Brooks, Brinson, McClellan, Stackhouse, Ford, Riley, Campbell, Crumedy, Ester. - This looks very solid now. Plus, Riley probably starts on the PUP if you need another body later. Plus, LVN probably rushes the passer from one of these positions in nickel or dime defenses.
OLB(5): Parsons, LVN, Sorrell, Oliver, DDS, Cox, Mosby, Barnett. Decent talent here, but very inexperienced. If there is someone available, this might be helpful given Parsons is out for at least 4 games to start the season.
MLB (5): Cooper, Franklin, McDuffie, Hopper, Niemann, Welch, Quinn - Solid 5. Would love to see Hopper (upside) displace McDuffie (solid steady performer) this year. Not much for PS development. Welch is a decent Neimann insurance policy.
CB (6): Nixon, St-Juste, Cisse, Valentine, Jackson, Hadden, Bartholomew. I think everyone would like more of an upgrade here, but you pretty much have to get rid of Nixon or Valentine to justify and addition here.
S (4): McKinney, Williams, Bullard, Oladapo, Baldwin, Simpson, Perry, Kenion - Solid top 4. The last DB spot probably comes down between Hadden and whichever S is best on ST.
So my biggest post Draft needs:
Backup QB
Aaron Rodgers - just kidding!
Tyrod Taylor could do a pretty good Malik impression
Wouldn't surprise me if they do another post TC addition (trade or waiver).
Backup G
Greg Van Roten - Not sure if he'd take a backup G position, but if not, there are a ton of other experienced Gs that could easily take Jennings' spot.
Experienced OLB
Haason Reddick, Von Miller - VonMiller could be very interesting across from Parsons come the playoffs.
Blocking TE but still a reception threat (i.e. Marcedes Lewis clone)
David Njoku - might be too $$, but now (post-draft) he might be reasonable.
Darren Waller - Not the blocking TE I suggest, but a long time Packer target.
CB upgrade for Nixon/Valentine
Marshon Lattimore - again it might take a bunch of $$, but even a one year deal might be worth it.
Sneed - injury prone the last two years, but solid with KC.
Diggs - Unless he thought he was going to get a big deal, I assume the Packer's interest has passed.
