Several players helped their case for making the 53-man roster or the practice squad.  

Packers played 71 offensive snaps.  Runyan and Myers looked like starting offensive linemen.  Jake Hanson got a long look at left guard before moving to center.  The aftermath of that is that the Packers have questions at right guard and perhaps right tackle.  Hanson drew two flags for hands to the face, though one was declined.  The starters had some difficulty with getting a good push when the team needed a yard.  The pass protection was largely acceptable, though the Forty Niners did not play Bosa, Armstead, or Ebukam.  The Packers averaged 4.1 yards per carry, but just 3.13 yards in the first half (with the five starters in), excluding Love's scrambles and one designed run.     

Romeo Doubs was removed after 28 snaps, and he played no snaps on special teams.  It appears to me as though the Packers have him penciled in as a starting wide receiver in "11" personnel.  Doubs played the "X" spot quite a bit.  At least against second string defensive backs, he was able to get open deep twice, and he clearly was the go to player for Jordan Love.  Doubs had one drop and one pass that was taken away from him, and drops have been an issue for him in practice.  

Amari Rodgers looked more agile and showed much better burst.  He handled his fair catches well and had a big return on a kickoff return.  He did not catch his first pass until the fourth quarter despite playing a ton of snaps, and that pass was a quick hitter behind the line of scrimmage.  He looked better but he did not get open downfield.  Winfree caught three passes for 27 yards in the first half.  I did not see Winfree play in the second half, which may or may not have significance.  It looked like they put Doubs in bubble wrap.  In Winfree's case, he might have tweaked something or the Packers might simply have wanted to see more of Toure and Davis.  Toure and Danny Davis also caught passes in the first half.  

Etling completed 6 of 8 passes for 123 yards.  Toure caught 2 of those 3 for 19 yards from Etling.  Amari Rodgers caught one pass for 22 and a TD, Baylor caught 2 of 2 for 75 yards including one for 68 yards. Hyman caught 1 for 7 yards.  Tyler Davis could not handle a high bullet from Love, instead tipping it into the air for an interception.  Deguara caught 2 of 3 for 12 yards, all in the first half.  The other TEs did little of note.

Jordan Love looked better, overall.  His footwork looked better if not perfect.  He had some zip on some balls, and he can run pretty well.  He did have some issues with ball placement and accuracy, but also threw some nice passes.  Two of his interceptions should have been caught by his intended targets.  The most egregious looking interception was the pass intended for Amari Rodgers, which appeared to have no chance of being completed.  Coach LaFleur said that two receivers ran the wrong route, though I am not sure which two.  One might have been Amari Rodgers, or perhaps the wrong routes were run by others, and that messed up the spacing, allowing CB Samuel Womack (Round 5 rookie) to be in an unexpected place.  Love still needs to see the CB.  Regardless, Jordan Love will be the backup quarterback.  He looked better to me and he has time to show more.

The defensive line is deep.  Heflin looks like a player who belongs on someone's 53-man roster.  Chris Slayton had a big night with 6 tackles (3 solo) with one tackle for loss.  Ford had a holding penalty but looked stout, as did TJ Slaton.  The Packers only gave Quay Walker two series before yanking him off the field.  WRs Danny Gray and Ray McCloud burned the defensive secondary a couple of times, catching passes for 76, 39, and 24 yards.  Gafford looked interesting, but he had his ankles broken and was beaten deep for one touchdown.  Nixon looked better than expected, though it is a little surprising that he got just 4 special teams snaps.  Jean-Charles and Enagbare looked competent. 

Crosby's roster spot is locked in, even if he is not ready in time for week one.  The Packers might not be able to afford putting him on IR.  

I was a little surprised that Rasheed Walker did not get a snap.  I think it is noteworthy that Caleb Jones got 25 snaps.

San Francisco did play a couple of "starters" on the offensive line, but Brendl has only played 250 snaps since coming into the NFL, and just 6 snaps in 2021 with zero in 2019 and 2020.  Banks played just 5 snaps as a rookie last year.  McKivitz played 70 snaps last season and 300 in 2020.  These are not real front line starters other than McGlinchey.  San Francisco played a well-traveled starting nickelback in Darqueeze Denard, and starting strong safety Talafonoa Hufanga, plus whatever one considers Javon Kinlaw to be, other than a very underwhelming high draft pick.  San Francisco played seven more position players than the Packers did. 

I have read some comments suggesting that the Forty-Niners played more starters than the Packers did.  I do not think that is accurate.  I do not think they played very many true starters.  Indeed, the Packers played Nijman, Runyan, Myers, and Newman, four starters from last year.  If folks know San Francisco's team better than I do, please comment below.  I used depth charts from ESPN and Ourlads to assist me with this section.   

From a roster construction perspective, I would suggest that the following players helped themselves quite a bit: Shemar Jean-Charles, Kingsley Enagbare, Chris Slayton, Jack Heflin, Isaiah MdDuffie, Kobe Jones, Amari Rodgers, Samori Toure, Danny Davis, and Juwan Winfree.  Some of those players are looking more at making the practice squad than at making th 53-man roster, but there is still time.
