Excelente, Ryan! Muchas gracias
Fun to be able to compare notes, Ryan, but yours are more thorough and perhaps cover more areas and depths of course. I won’t do this again since you’re doing it and doing it better, but since I have already written these notes down, I though I should share it anyway. Plus, I don’t have access to All-22 or other film study sites. What I get from an actual televised game is where I form my thoughts and opinions on plays and players.
From the preseason game (my notes are biased towards LBs and defense):

Troy Dye: Dye played the whole first half and then was replaced by Shane Lee. Early in the first half Henley and Dye dropped back too deep beyond the first-down marker into the safety’s zone where passes went for 1st It happened at least twice. In one play, Dye didn’t stay with his assignment on the RB before he realized hit but has given him almost 15 yards of cushion already which resulted in a first down to Seattle on a wide swing pass to the RB. He played better in the open field than in traffic where he lacks the strength, technique to shed blocking, and played too tall. He got stood up by the RB (Holani of the Seahawks) and was no match for the TE he went up against. In one particular play where the QB scrambled for a first down thru the middle, Dye was at the Mike spot and instead of jamming the RB to set himself up to make a play on the QB, he got screened instead. Dye had some bright moments but they weren’t enough. He’s got some areas to improve in including playing strength, pad level playing, and play recognition. I think he’s a better fit as a backup at the Will spot behind Henley and Niemann, but not at the Mike spot where Denzel and Colson will share time. It could be that Minter just wanted to see Dye playing to evaluate his playing ability against the 1s and 2s.

Henley: I think he showed a lot of what he is capable of and expected of him. He’s instinctive, a solid tackler, and physical enough in traffic against blocking even though a little hesitant at times thru his gap assignments. He isn’t quite physical as Denzel or Jr Colson to be expected but the Will spot is best suited for him. He is a sideline-to-sideline backer with excellent coverage skills to be excited about, and he’s a good communicator.
Niemann: He’s a capable Will-LB2 behind Henley. I love how low his pad level is when he’s on the field. For a 6’-3” (244 lbs) guy, he plays low like he’s 5’-10”. He’s got excellent speed. But he just needs to play loose more and not being trigger-shy when it comes to tackling when he has the advantage over the ball carrier. He would be the first to tell us he had a brain fart on the second play he was in to replace Henley. On Seattle’s TD pass to the TE, Niemann hesitates to launch at the TE for an easy tackle from a side angle on the target but instead he rushes up to bear tackle him, the TE instead had just the time he needed to fake a forward lean then a back spin to make him miss. Once you have the side angle on a ball carrier, you can’t be trigger-shy to launch while in range. One second you give a ball carrier is an advantage you’ve ceded.
Tuli: I agreed. He’s got nothing more to prove. Even with Mack and Bosa, I think Tuli will have a monster season this year in Minter’s defense. He’s got a different switch that he turns on when he is up against a real opponent. He looks even more decisive and explosive this year. Him and Bosa to alternate on the inside from the edge is something to watch this year.

         I’m biased for sure since I’ve met Tuli and his family before he was a Charger and last met them at their church’s annual national-wide conference in Riverside, California in April this year. I did the civil and structural engineering for their church headquarter in Riverside where they host their annual conference. I have since been an invited guest to their annual festival, a part of their conference gathering for over 5 years now. Not only that, I got to know Tuli’s father Niu thru a cousin of mine who used to employ Tuli’s dad and attended the same church with Tuli’s family. Tuli’s dad last year said he would get me and my cousin some tickets to the game. Not sure when those tickets would show up. 😆 
        I found it funny, the older women and some of Tuli’s aunts at the festival still tell Tuli at the end of the festival to carry their stuff and load them up in their vehicles every year, which Tuli did willingly with “yes aunty” and a smile. Tuli and his brother (Marlon) who is with the Philadelphia Eagles were taking down the all the big tents and loading them up on a flatbed truck. Tuli is a humble kid from a very good family.

Shane Lee: He came in to replace Troy Dye in the 2nd half. I agree, he didn’t show much in either the run and passing defense. It might be too early, but I didn’t see anything to make me think there is role for him in this defense. The coverage skill isn’t there. He’ll be lucky to get a spot in the PS.
 Tre’mon Morris-Brash: He was a player I have been excited about since OTA. For how well he has proven himself as a solid backup OLB, it makes me to think he’s making the 53-man roster barring injury of course. Which means, Minter would carry 5 OLBs and 5 IDL unlike Staley’s defense which carried 4 OLBs and 6 IDLs while Tuli and Rumph also played SP with an injury prone Joey Bosa, while 2 IDL never once left the bench. Kyle Van Noy left unsigned to sign with the Ravens.
Morgan Fox: Could have his best season from the 5-tec / 3-tec spot in Minter’s defense. He stood out in just a couple of plays. He lined up from the 3-tec and immediately got thru the line to make the play.    
Ogbonnia: In limited snaps in the first half, I thought he was dominating. He showed a lot in his rookie season, but with the injury last year, I was expecting him to show a lot more this year. If he stays healthy, he’s another to have a solid season. He could become the real DT Minter is looking for to pair up with Ford at NT. From what I’ve seen from the others, it is Otito’s starting job to lose.
CJ Okoye:  CJ went in for just a couple of plays in the last 3 minutes of the game. I thought he and Clark pushed the middle of the pocket well to stop the inside run attempts. CJ is too talented, very athletic, too powerful, and a giant of a man not to get more playing opportunity for his growth in the defense. I hope he’ll get more opportunity to play in the last 2 preseason games. He should be able to grasp the IDL role quickly now in his 2nd season as suppose to playing OL which is harder to learn especially for someone who had never played the game or position before.  
Bosa: Joey once said at the beginning of training camp that he is not expecting to drop back to cover in this new defense. It sounds like Bosa will be providing inside pass rush when the play calls for one or both of the edge rushers to drop into coverage.
 Minter’s Defense:  For someone who loves defense, Minter’s defense and play calling have me so pumped up now for the season to start already even though there is still a big question mark at IDL. The defensive back unit has made me to believe it’s better than the below average rating I had given them before training camp. The safeties with James and Gilman as anchors, it’s a solid unit. I hope Tony Jefferson makes the roster. He lacks straight line speed but plays fast still. You’re only as fast as you process plays, play anticipation, and playing with confidence. That’s something he possessed over the others.    
Roman’s Offense: Roman’s preseason offense supposed to be a simple, straight forward offense. BUT I expected it to have a better showdown against a Mike Macdonald’s defense after seeing Minter’s defense everyday in practice, which has a lot of similarities and same philosophy. To me it was very disappointing. The IOL is still a big question mark. The small sample size from Pipkins wasn’t very encouraging and I hope Bozeman isn’t a rag doll like Jaimes who Bryon Murphy consistently buried behind the LOS with Murphy’s own name and photo on his tombstone.
